#5 fix do_one_loop caller() warning.

[Anonymous]

when running Net::IRC (0.75 and CVS) under 'perl -w'
and using do_one_loop you see the following warning:

Use of uninitialized value in string eq at
/usr/lib/perl5/site_perl/5.8.4/Net/IRC.pm line 141.

i'm guessing the results from caller() are simply empty
when not coming from flush_output_queue which leads to
the error. attached diff resolves the warning.

while you're at it, s/project/projects/ on line 32 of
README.

thank you.
