* Remember the number of lines scrolled into the history (versus clearednicm2016-09-021-2/+2

* Don't update cells in each block of data read from a pane immediately,nicm2016-07-151-62/+218
| | | | | | instead track them as change (dirty) and update them once at the end, saves much time if repeatedly writing the same cell. Also fix comparison of cells being equal in a few places (memcmp is not enough).

* Remove support for the UTF-8 mouse extension. This was a briefly used,nicm2015-11-231-2/+2
| | | | | | | | poor idea that was fairly quickly replaced by SGR mouse input (which is now widespread). It is impossible to tell the difference between UTF-8 and non-UTF-8 mouse input; since the mouse-utf8 option was removed tmux has not handled it correctly in any case; and it is ridiculous to have three different forms of mouse input.

* Long overdue change to the way we store cells in the grid: now, insteadnicm2015-11-131-51/+43
| | | | | | | | | | | | | | | of storing a full grid_cell with UTF-8 data and everything, store a new type grid_cell_entry. This can either be the cell itself (for ASCII cells), or an offset into an extended array (per line) for UTF-8 data. This avoid a large (8 byte) overhead on non-UTF-8 cells (by far the majority for most users) without the complexity of the shadow array we had before. Grid memory without any UTF-8 is about half. The disadvantage that cells can no longer be modified in place and need to be copied out of the grid and back but it turned out to be lot less complicated than I expected.

* Two improvements to reflow from Balazs Kezes:nicm2014-11-081-3/+1
| | | | | | | | - Don't extend the line to full width on insert/delete character which means leaves extra spaces when reflowing. - Only mark a line wrapped when the cursor actually goes off the end, not on newlines which can be used for positioning.

* Allow replacing each of the many sets of separate foo-{fg,bg,attr}nicm2014-01-281-85/+2
| | | | | | | | | | | | | | | | | | | | | | | | | options with a single foo-style option. For example: set -g status-fg yellow set -g status-bg red set -g status-attr blink Becomes: set -g status-style fg=yellow,bg=red,blink The -a flag to set can be used to add to rather than replace a style. So: set -g status-bg red Becomes: set -ag status-style bg=red Currently this is fully backwards compatible (all *-{fg,bg,attr} options remain) but the plan is to deprecate them over time. From Tiago Cunha.

| | | | | | | this is used and the application has requested bracketed pastes, then tmux surrounds the pasted text by \033[200~ and \033[201~. Applications like vim can (apparently) use this to avoid, for example, indenting the text. From Ailin Nemui.
