Thanks.

It is wrong to use SLASH_STRING to search for directory separators;
that is non-portable.  SLASH_STRING is for constructing file names
from directories and the basename.

To look for directory separators, please use lbasename, ldirname, or
similar functions, which already know about possible separators on
each supported platform.

This should use "filenames", not "a filename", since the option
affects any displayed file name, not just one of them.

This is ambiguous.  I suggest to say "The default is \"relative\"."

Sorry for not paying attention when you first posted the patch.
