The type "enum" replaces type "integer" when used with string values.
For compatibility, any option created with type "integer" and string values is
automatically created to "enum" on creation, with no error.
This fixes a bug where if you had multiple lines in the input and
pressed ctrl-w when the cursor was after the first word of any line but
the first, it would delete both the word before the cursor and the last
word on the preceding line.
For example typing this on core buffer:
/t1
/t2
was not executing the two commands but sent the text to the buffer instead.
This is because WeeChat thinks it's a path, and the newline should indicate
it's not (like a space before the next slash: "/t1 /t2" is a command, not a
path, but "/t1/t2" is considered a path).
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).
This changes the commands delete_beginning_of_line, delete_end_of_line,
delete_line, move_beginning_of_line and move_end_of_line to operate on
the current line instead of the whole input. The commands
delete_beginning_of_input, delete_end_of_input, delete_input,
move_beginning_of_input and move_end_of_input are added with the
previous implementations that the line commands had.
Additionally, the commands move_previous_line and move_next_line are
added which moves the cursor to the previous/next line and keeps the
horizontal position in the line.
The meta-r key is changed from delete_line to delete_input to keep the
behavior, and because you probably want to delete the whole input more
often than the line. The meta-R key is added for delete_line.
The home, end, ctrl-u and ctrl-k keys are kept to the same commands,
which means that they change behaviour. This is because having them
operate on the line is consistent with other applications (vim, zsh),
and I also think it's more practical.
These new bindings are added:
shift-home: /input move_beginning_of_input
shift-end: /input move_end_of_input
shift-up: /input move_previous_line
shift-down: /input move_next_line
meta-R: /input delete_line
meta-ctrl-u: /input delete_beginning_of_input
meta-ctrl-k: /input delete_end_of_input
