Appending `.lock` seems fine to me (note the period rather than hyphen).  I
don't find it ugly, instead explanatory!  If users do see these file names,
then it is clearer that they are lock files.  There is precedent for use of
this file extension[0], and there's also lots of precedent for stacking
file extensions.

I propose keeping the traditional `.#` prefix but adding a `.lock` suffix.
