Contents of ~/.weechat/weechat.conf and other config files are sometimes disappear after a power outage or other crash.
This was probably caused by the fact that some filesystems are unable rename a file atomically if the rename doesn't overwrite another file.

More information about overwrite-by-rename: http://btrfs.ipv5.de/index.php?title=FAQ#What_are_the_crash_guarantees_of_overwrite-by-rename.3F

I attach a simple patch that may fix the problem.
