mingw.h: permit arguments with side effects for is_dir_sep

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++) Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
