Add mode keys to move the cursor to the top, middle and bottom of the screen.
H/M/L in vi mode and M-R/M-r in emacs (bottom of screen not bound in emacs).
Do this in a better way - print messages when exiting with nonzero.
Also remove the login shell information from server-info, only the client
should care about it.
When drawing lines that have wrapped naturally, don't force a newline but
permit them to wrap naturally again. This allows terminals that use this to
guess where lines start and end for eg mouse selecting (like xterm) to work
correctly.
This was another long-standing issue raised by several people over the last
while.
Thanks to martynas@ for much testing. This was not trivial to get right so
bringing it in for wider testing and adn to fix any further glitches in-tree.
When backspace is received at the beginning of a line and the previous line was
wrapped, move the cursor back up to the end of the previous line.
Another one of the forgotten persons requested this quite a while ago (I need
to start noting names on todo items...) when it was quite hard to
implement. Now it is easy and I don't see it can do any harm, so hey presto...
Don't run through the column unchanged case if the row was unchanged but there
were no suitable optimisations, instead make it an else to fall through to
absolute addressing.
Use relative cursor movement instead of absolute when possible and when
supported by the terminal to reduce the size of the output data (generally
about 10-20%).
Like linefeed, don't set the scroll region for reverse index unless it will be
needed.
While here, also tidy up a couple of long lines and remove an extraneous blank.
Set the current window pointer to NULL when killing a winlink that is to be
replaced with link-window -k. This prevents it being pushed onto the last
window stack and causing a use-after-free.
Only took me an hour to find this :-/...
Add a pipe-pane command to allow a pane to be piped to a shell command, for
example:
pipe-pane 'cat >~/out'
No arguments stops outputing and closes the pipe; the -o flag toggles a pipe
and on and off (useful for key bindings).
Suggested by espie@.
Clean up by introducing a wrapper struct for mouse clicks rather than passing
three u_chars around.
As a side-effect this fixes incorrectly rejecting high cursor positions
(because it was comparing them as signed char), reported by Tom Doherty.
