[bug #62572] [gropdf] would like complaint if embedding needed but download file useless

[Deri James]

Follow-up Comment #1, bug #62572 (project groff):

I'm not sure how to do this, it is quite permissable to have a blank download
file, just as it is in grops. The file in grops lists those fonts which
require to be embedded since they are not part of the 35 base fonts for
postscript. In gropdf a missing entry also means that the font does not need
to be downloaded, i.e. it is one of the base pdf fonts, but because I
implemented the -e flag in gropdf I do need to know from where the base fonts
can be downloaded. This is why some of the filenames in download have a
leading asterisk, they are base files which don't need to to be included in
the pdf except when the -e flag is present.

Gropdf should not be expected to work without a valid download file, which is
why I consider removing BuildFoundries from groff executables was a mistake.
It was intended as a tool for the user to use if there were changes to his
system which resulted in new positions for the needed fonts, i.e. new version
of ghostscript. This is why the program attempts to preserve local changes to
download while looking for the URW fonts. It could similarly be used if a user
messed up his download file.

Gropdf could have a moan if the -e flag is present and the required font is
not mentioned in the download file, but without the flag it just means that no
download is required, the same as grops.
