I was a bit confused by the oneline. Maybe something like
mingw.h: avoid side effects with is_dir_sep()'s argument
Taking git-compat-util.h's cue (which uses an inline function
to back is_dir_sep()), let's use an inline function to back
also the Windows version of is_dir_sep(); This avoids problems
when calling the function with arguments that do more than just
provide a single character, e.g. incrementing a pointer. Example:
is_dir_sep(*(p++))

The patch is very good, of course.
