(fhpd) load /usr/bin/b<tab>
Doesn't try to complete the file name.
But the identical thing for the run command does do file completion of the
(fhpd) run /usr/bin/b<tab>
OK, the original report was bogus.
The real issue was that neither command autocompletes for relative files
(absolute files starting with / are fine for both run and load).
Changed the subject to mention that it is about relative file paths.
This also doesn't work when prefixed with ./
(fhpd) run ./<tab>
Need to consider a new import.
