How to make Midnight Commander exit to it's current directory

[poma]

Hello

Fedora 26 switched to /var/tmp ...
- "Not enough disk space for midnight commander in /tmp"
  https://bugzilla.redhat.com/show_bug.cgi?id=895444
- "Downstream-only patch to make mc use /var/tmp for large temporary files (RHBZ#895444)."
  https://src.fedoraproject.org/cgit/rpms/mc.git/commit/mc-tmpdir.patch?id=73d...

... but not entirely, therefore
- "Extends TMPDIR_DEFAULT to mc-wrapper scripts - exit to CWD"
