#29 Allow reading input filenames from stdin

[Wesley J. Landaker]

I'm forwarded this from the Debian BTS:

<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=355969>

Basically, par can operate over lots of files, but
the number is limited either by the command line, or
by what can be described with wildcards.

One good way to get around this limitation is to have
an option for par2cmdline to read the list of
filenames from stdin instead of from the command
line, then someone could do e.g.:

$ find . <complecated expression> |
par <stdin filename option>

Please take a look at the URL to the Debian BTS to
see more information from the original reporter. =)

Thanks!
