A not-so-common mistake is to write a script to feed "git bisect

Add "fast_unwind_on_malloc=0" to LSAN_OPTIONS to get more meaningful
stack traces from LSAN. This isn't required under ASAN which will emit
traces such as this one for a leak in "t/t0006-date.sh":
$ ASAN_OPTIONS=detect_leaks=1 ./t0006-date.sh -vixd
[...]
Direct leak of 3 byte(s) in 1 object(s) allocated from:

SUMMARY: AddressSanitizer: 3 byte(s) leaked in 1 allocation(s).

Whereas LSAN would emit this instead:
$ ./t0006-date.sh -vixd
[...]
Direct leak of 3 byte(s) in 1 object(s) allocated from:

SUMMARY: LeakSanitizer: 3 byte(s) leaked in 1 allocation(s).

Now we'll instead git this sensible stack trace under
LSAN. I.e. almost the same one (but starting with "malloc", as is
usual for LSAN) as under ASAN:
Direct leak of 3 byte(s) in 1 object(s) allocated from:

As the option name suggests this does make things slower, e.g. for
t0001-init.sh we're around 10% slower:
$ hyperfine -L v 0,1 'LSAN_OPTIONS=fast_unwind_on_malloc={v} make T=t0001-init.sh' -r 3
Benchmark 1: LSAN_OPTIONS=fast_unwind_on_malloc=0 make T=t0001-init.sh
Time (mean ± σ): 2.135 s ± 0.015 s [User: 1.951 s, System: 0.554 s]
Range (min … max): 2.122 s … 2.152 s 3 runs
Benchmark 2: LSAN_OPTIONS=fast_unwind_on_malloc=1 make T=t0001-init.sh
Time (mean ± σ): 1.981 s ± 0.055 s [User: 1.769 s, System: 0.488 s]
Range (min … max): 1.941 s … 2.044 s 3 runs
Summary
'LSAN_OPTIONS=fast_unwind_on_malloc=1 make T=t0001-init.sh' ran
1.08 ± 0.03 times faster than 'LSAN_OPTIONS=fast_unwind_on_malloc=0 make T=t0001-init.sh'
I think that's more than worth it to get the more meaningful stack
traces, we can always provide LSAN_OPTIONS=fast_unwind_on_malloc=0 for
one-off "fast" runs.

Change the GIT_BUILD_DIR from a path like "/path/to/build/t/.." to
"/path/to/build". The "TEST_DIRECTORY" here is already made an
absolute path a few lines above this.
We could simply do $(cd "$TEST_DIRECTORY"/.." && pwd) here, but as
noted in the preceding commit the "$TEST_DIRECTORY" can't be anything
except the path containing this test-lib.sh file at this point, so we
can more cheaply and equally strip the "/t" off the end.
This change will be helpful to LSAN_OPTIONS which will want to strip
the build directory path from filenames, which we couldn't do if we
had a "/.." in there.

Correct a misleading comment added by me in 62f539043c7 (test-lib:
Allow overriding of TEST_DIRECTORY, 2010-08-19), and add an assertion
that TEST_DIRECTORY cannot point to any directory except the "t"
directory in the top-level of git.git.
This assertion is in effect not new, since we'd already die if that
wasn't the case[1], but it and the updated commentary help to make
that clearer.
The existing comments were also on the wrong arms of the
"if". I.e. the "allow tests to override this" was on the "test -z"
arm. That came about due to a combination of 62f539043c7 and
85176d72513 (test-lib.sh: convert $TEST_DIRECTORY to an absolute path,
2013-11-17).
Those earlier comments could be read as allowing the "$TEST_DIRECTORY"
to be some path outside of t/. As explained in the updated comment
that's impossible, rather it was meant for *tests* that ran outside of
t/, i.e. the "t0000-basic.sh" tests that use "lib-subtest.sh".
Those tests have a different working directory, but they set the
"TEST_DIRECTORY" to the same path for bootstrapping. The comments now
reflect that, and further comment on why we have a hard dependency on
this.

Change our ASAN_OPTIONS and LSAN_OPTIONS to set defaults for those
variables, rather than punting out entirely if we already have them in
the environment.
We want to take any user-provided settings over our own, but we can do
that by prepending our defaults to the variable. The libsanitizer
options parsing has "last option wins" semantics.
It's now possible to do e.g.:
LSAN_OPTIONS=report_objects=1 ./t0006-date.sh
And not have the "report_objects=1" setting overwrite our sensible
default of "abort_on_error=1", but by prepending to the list we ensure
that:
LSAN_OPTIONS=report_objects=1:abort_on_error=0 ./t0006-date.sh
Will take the desired "abort_on_error=0" over our default.
See b0f4c9087e1 (t: support clang/gcc AddressSanitizer, 2014-12-08)
for the original pattern being altered here, and
85b81b35ff9 (test-lib: set LSAN_OPTIONS to abort by default,
2017-09-05) for when LSAN_OPTIONS was added in addition to the
then-existing ASAN_OPTIONS.

The script uses "git show -s" to display the title of the merge
commit being studied, without explicitly disabling the pager, which
is not a safe thing to do in a script.
For example, when the pager is set to "less" with "-SF" options (-S
tells the pager not to fold lines but allow horizontal scrolling to
show the overly long lines, -F tells the pager not to wait if the
output in its entirety is shown on a single page), and the title of
the merge commit is longer than the width of the terminal, the pager
will wait until the end-user tells it to quit after showing the
single line.
Explicitly disable the pager with this "git show" invocation to fix
this.
The command uses the "--pretty=format:..." format, which adds LF in
between each pair of commits it outputs, which means that the label
for the merge being learned from will be followed by the next
message on the same line. "--pretty=tformat:..." is what we should
instead, which adds LF after each commit, or a more modern way to
spell it, i.e. "--format=...". This existing breakage becomes
easier to see, now we no longer use the pager.

It is helpful to distinguish between a 'working tree' and a 'worktree'.
A worktree contains a working tree plus additional metadata. This
metadata includes per-worktree refs and worktree-specific config.
This is the last of multiple changes to git-worktree.txt, starting at
the LIST OUTPUT FORMAT section.
The EXAMPLES section has an instance of "working tree" that must stay as
it is, because it is not talking about a worktree, but an example of why
a user might want to create a worktree.
