Test t4018-diff-funcname.sh should pass. As Johan mentioned, in the
last patch '\\s' should have been converted to '[ \t]', rather than
to just ' ', but that should not affect the test and should only
affect html, python, and ruby patterns.
It would be nice if the tests were expanded.
I expect they will be in Junio's tree soon, most likely the master
branch.
"\t" is safe to use since it is interpreted by git in config.c: parse_value(),
not by the regex library. I was also concerned about that character until I
traced the code to parse_value(). Junio is right that better documentation of
this feature is needed.
