Tags: patch Hi, Someone on Libera recently observed their messages being split into much smaller chunks than expected. And apparently this problem isn't much of a secret either. It seems to boil down to `erc-split-line's reliance on `fill-region' for rejiggering messages on their way out the door. If you poke around that area long enough, you'll see that all that fill-related figuring happens column-wise, which means messages always fall under the protocol limit (and thus the radar). I've made an attempt at correcting this, but it'd be nice if someone better versed in Emacs fundamentals could take a quick look. (All the doing happens in the second patch, in the new function `erc--split-line'.) Thanks.
