These variables are the same as "_chat_bol" and "_chat_eol" except that they
stop at the beginning of the focused line (not the whole message displayed, in
case message has multiple lines separated by "\n").
This contains the single line that you focused on, like _chat_word
contains the word that you focused on. This will be equal to
_chat_line_message if the chat line only contains a single line, but if
the chat line has multiple lines, _chat_line_message will contain all of
them, but _chat_focused_line will only contain the single line that was
focused.
Fixes part of #1913
This pointer is the first argument received by callbacks, and the
existing argument "data" is now automatically freed by WeeChat when the
object containing the callback is removed.
With this new pointer, the linked list of callbacks in scripts has been
removed. This will improve speed of scripts (using a lot of hooks),
reduce memory used by scripts and reduce time to unload scripts.
