Replace use of strbuf_addf() with strbuf_add() when enumerating
loose objects in for_each_file_in_obj_subdir(). Since we already
check the length and hex-values of the string before consuming
the path, we can prevent extra computation by using the lower-
level method.
One consumer of for_each_file_in_obj_subdir() is the abbreviation
code. OID abbreviations use a cached list of loose objects (per
object subdirectory) to make repeated queries fast, but there is
significant cache load time when there are many loose objects.
Most repositories do not have many loose objects before repacking,
but in the GVFS case the repos can grow to have millions of loose
objects. Profiling 'git log' performance in GitForWindows on a
GVFS-enabled repo with ~2.5 million loose objects revealed 12% of
the CPU time was spent in strbuf_addf().
Add a new performance test to p4211-line-log.sh that is more
sensitive to this cache-loading. By limiting to 1000 commits, we
more closely resemble user wait time when reading history into a
pager.
For a copy of the Linux repo with two ~512 MB packfiles and ~572K
loose objects, running 'git log --oneline --parents --raw -1000'
had the following performance:
HEAD~1 HEAD

"git grep -W", "git diff -W" and their friends learned a heuristic
to extend a pre-context beyond the line that matches the "function
pattern" (aka "diff.*.xfuncname") to include a comment block, if
exists, that immediately precedes it.
* rs/include-comments-before-the-function-header:
grep: show non-empty lines before functions with -W
grep: update boundary variable for pre-context
t7810: improve check of -W with user-defined function lines
xdiff: show non-empty lines before functions with -W
xdiff: factor out is_func_rec()
t4051: add test for comments preceding function lines

"git branch --list" learned to show its output through the pager by
default when the output is going to a terminal, which is controlled
by the pager.branch configuration variable. This is similar to a
recent change to "git tag --list".
* ma/branch-list-paginate:
branch: change default of `pager.branch` to "on"
branch: respect `pager.branch` in list-mode only

"git branch" and "git checkout -b" are now forbidden from creating

branch: split validate_new_branchname() into two
branch: streamline "attr_only" handling in validate_new_branchname()

Let's make it clear how patches should flow into
contrib/git-jump. The normal Git maintainer does not
necessarily care about things in contrib/, and authors of
individual components should be the ones giving the final
review/ack for a patch. Ditto for bug reports, which are
likely to get more attention from the area expert.
