LUCY-174 Regex glitch breaks dir name.
LUCY-174 Regex glitch breaks dir name.

A broken regex which is intended to change a filepath extension from ".c" to
e.g. ".o" will instead result in a broken directory name if Lucy is being
built in a directory which contains the string ".c" – for instance,
"/home/foo/.cpan/build/".
