Subject: don't abs_path($ENV{MR_CONFIG})
X-Git-Url: https://git.madduck.net/code/myrepos.git/commitdiff_plain/55aa3f5eb153f5e46a5d795bc3fd40fa3f35646b

don't abs_path($ENV{MR_CONFIG})

mrconfig files can be symlinks to files in other directories. But the directory
the file is is significant, as it's the directory paths in the file
are relative to. abs_path follows the symlink, so take care not to use it.
