Watcher always sends notifications after updating published comments

Watcher sends notifications after comment updates all the time because it mistakenly believes the author of every comment is user 0.

The error is in the _watcher_hook_comment_update() function and it is because on the $comment_author line $comment is spelled incorrectly with 3 m's both times.

I have applied multiple patches to watcher to fix bugs and add features so my line numbers will not match with the released versions so here is the simple patch in text form:
