We display empty diffs for files whose timestamps have changed.
Usually, refreshing the index makes those empty diffs go away.
However, when not using the index they are not very useful and
there is no option to suppress them.
This forces on the skip_stat_unmatch option for diff --no-index,
suppressing any empty diffs. This option is also used for diffs
against the index when "diff.autorefreshindex" is set, but that
option does not apply to diff --no-index.

We forgot to move to the next argument when parsing -q, getting stuck
in an endless loop.

We need to parse options before we can see if --exit-code was
provided.

Accept -- as an "end of options" marker even when using --no-index.
Previously, the -- triggered a "normal" index/tree diff and subsequently
failed because of the unrecognized (in that mode) --no-index.
Note that the second loop can treat '--' as a normal option, because
the preceding checks ensure it is the third-to-last argument.
While at it, fix the parsing of "-q" option in --no-index mode as well.

With a new configuration "diff.mnemonicprefix", "git diff" shows the
differences between various combinations of preimage and postimage trees
with prefixes different from the standard "a/" and "b/". Hopefully this
will make the distinction stand out for some people.
"git diff" compares the (i)ndex and the (w)ork tree;
"git diff HEAD" compares a (c)ommit and the (w)ork tree;
"git diff --cached" compares a (c)ommit and the (i)ndex;
"git-diff HEAD:file1 file2" compares an (o)bject and a (w)ork tree entity;
"git diff --no-index a b" compares two non-git things (1) and (2).
Because these mnemonics now have meanings, they are swapped when reverse
diff is in effect and this feature is enabled.

The name path_list was correct for the first usage of that data structure,
but it really is a general-purpose string list.
$ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list)
$ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list)
$ git mv path-list.h string-list.h
$ git mv path-list.c string-list.c
$ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path)
$ perl -i -pe 's/path/string/g' string-list.[ch]
$ git mv Documentation/technical/api-path-list.txt \
Documentation/technical/api-string-list.txt
$ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths)
... and then fix all users of string-list to access the member "string"
instead of "path".
Documentation/technical/api-string-list.txt needed some rewrapping, too.

Even when inside a git work tree, if two paths are given and at least one
is clearly outside the work tree, it cannot be a request to diff a tracked
path anyway; allow such an invocation to use --no-index semantics.

Even if "foo" and/or "bar" does not exist in index, "git diff foo bar"
should not change behaviour drastically from "git diff foo bar baz" or
"git diff foo". A feature that "sometimes works and is handy" is an
unreliable cute hack.
"git diff foo bar" outside a git repository continues to work as a more
colourful alternative to "diff -u" as before.
