#2 Allow start URLs to be piped to checkbot

[Hans de Graaff]

Alternatively they could be read from a file.

See original request received by email:

First the enhancement: Since some OSes have limited
command line lengths, it would be nice to pipe URLs to
the script or read them from a file instead of having
to specify them on the command line, something like

unshift(@ARGV, $main::opt_url) if $main::opt_url;

if (scalar(@ARGV) == -1) {
unshift(@ARGV, <>);
}

(and disabling the check if url= was specified or urls
were given on the command line) might do.
