Right. So I wanted to avoid that rathole by requiring absolute
pathnames on the command line (realpath() should work fine on Linux,
but, being a nonstandard---even if widely available function---might
not be there on other systems; besides the CAVEATS section of its man
page on FreeBSD mentions that Solaris realpath() `will, under certain
circumstances, return a relative resolved_path when given a relative
pathname').
The current behavior of silently treating relative paths as relative
to `/' clearly violates the Principle Of Least Astonishment. It
should not be violated by bailing on relative pathnames and should not
inconvenience users too much.

OK, you convinced me that it might not be a good idea after all.
Clearing man catfiles (and, I now notice, teTeX METAFONT-generated pk
fonts) requires stmpclean-like functionality, so it makes sense to
make sure stmpclean can do that job.
How about I check for `/' as the first char of the pathname from the
command line and refuse to run if it's not there?
