Option parsing misses '-p'

[sbeitzel]

The command line argument processing doesn't detect the -p switch. For example:

[sbeitzel@PirateBook ~/src/github/abcm2ps]$ ./abcm2ps -p sample.abc
abcm2ps-8.13.16 (2017-10-24)
error: Unknown flag: -p ignored
File sample.abc

I'm attaching a patch which fixes this:

Fixed. Thanks.

Yep, that does the job.

Out of curiosity, why doesn't this application use getopt for parsing the options?

This an old application, started almost 20 years ago, which was also working in M$-DOS.
Then, as the command line arguments may be complex (global parameters + files + possible parameters for each file), it is simpler to parse them manually.
