Comment(by guanx):

 Replying to [ticket:180 metux]:
 > http://svn.mandriva.com/cgi-
 bin/viewvc.cgi/packages/cooker/mc/current/SOURCES/mc-
 concat.patch?view=markup

 Here: const char *file = filename;
 Why a separate variable for the filename pointer?

 And, in the patch, there is this comment:
 /* Is this one: *file == PATH_SEP seems to be not fully portable? */
 It's also confusing.
