Only check for ',' explicitly and handle both ')' and '\0' in the else
branch. strcspn() can only return ',', ')' and '\0' at this point so the
new code is completely equivalent to what we had before.
This also fixes following GCC warning:
setup.c: In function ‘get_pathspec’:
setup.c:207:8: warning: ‘nextat’ may be used uninitialized in this function
[-Wmaybe-uninitialized]
setup.c:205:15: note: ‘nextat’ was declared here
Signed-off-by: Lukas Fleischer <g...@cryptocrack.de>

This removes the only warning that currently occurs when building the
next branch.
Junio: Feel free to squash this into Andrew's patch (805da4dee15b,
"setup.c: stop prefix_pathspec() from looping past the end of string").
