Reason being, BTW, that a rename is implemented as an
efficient change of pointers inside inodes while renaming
files across filesystems would involve actually copying file
content.

The obvious fix is to create the new config file in the same
place as the old one:

1) write new config to ~/.gnumed/gnumed.conf.new overwriting
   any gnumed.conf.new that might exist
2) rename ~/.gnumed/gnumed.conf.new to ~/.gnumed/gnumed.conf
   which _will_ be on the same filesystem
