The speed of the built-in diff generator is nice; but the function names
shown by `diff -p' are /really/ nice. And I hate having to choose. So,
we hack xdiff to find the function names and print them.
xdiff has grown a flag to say whether to dig up the function names. The
builtin_diff function passes this flag unconditionally. I suppose it
could parse GIT_DIFF_OPTS, but it doesn't at the moment. I've also
reintroduced the `function name' into the test suite, from which it was
removed in commit 3ce8f089.
The function names are parsed by a particularly stupid algorithm at the
moment: it just tries to find a line in the `old' file, from before the
start of the hunk, whose first character looks plausible. Still, it's
most definitely a start.
