Subject: Tidy up FJOIN processing somewhat - don't bother faking a TS to get modes accepted... 
X-Git-Tag: v2.0.23~2346
X-Git-Url: https://git.netwichtig.de/gitweb/?a=commitdiff_plain;h=de8be466941204bf47c9ed821b2e5a0a79ae64f1;p=user%2Fhenk%2Fcode%2Finspircd.git

Tidy up FJOIN processing somewhat - don't bother faking a TS to get modes accepted, just use a high technology of programming known as an "if statement". Also add generous debug to this via snomask +d, as it seems the occasional desync is occuring.
