The API functions `command` and `command_options` (when `split_newline` = 0,
which is the default value) don't split on newline and then the first line is
executed and the subsequent lines (after "\n") are ignored.
There are no changes when the input has multiple lines filled by the user: the
split is done and multiple commands are executed (for example if the user is
pasting multiple commands to execute).
New options to customize behavior on signals received, with the default
behavior:
- weechat.signal.sighup: quit in normal mode, reload config in headless
- weechat.signal.sigquit: quit
- weechat.signal.sigterm: quit
- weechat.signal.sigusr1: no command executed by default
- weechat.signal.sigusr2: no command executed by default
The signals SIGUSR1 and SIGUSR2 are introduced by this commit, so it's now
possible to run commands when they are received.
The SIGHUP signal makes now WeeChat quit, it was the behavior before version
2.9 of WeeChat (see commit de1e61f7cd).
