fix(inccommand): restrict cmdpreview undo calls

2023-07-28T07:20:58Z

Problem: The cmdpreview saved undo nodes on cmdpreview_prepare() from ex_getln.c may become invalid (free) if the preview function makes undo operations, causing heap-use-after-free errors. Solution: Save the buffer undo list on cmdpreview_prepare)_ and start a new empty one. On cmdpreview_restore_state(), undo all the entries in the new undo list and restore the original one. With this approach, the preview function will be allowed to undo only its own changes. Fix #20036 Fix #20248

feat: multibuffer preview support for inccommand

2022-08-19T03:27:52Z

Allows preview callbacks to modify multiple buffers in order to show the preview. Previously, if multiple buffers were modified, only the current buffer would have its state restored. After this change, all buffers have their state restored after preview. Closes #19103.

fix(inccommand): avoid crash if callback changes inccommand option (#18830)

2022-06-01T19:48:36Z

clang: Result of operation is garbage or undefined clang: Uninitialized argument value Also check for == 's' instead of != 'n' as it is more straightforward. Also fix another unrelated PVS warning: PVS/V1071: Return value of win_comp_pos() is not always used

fix(inccommand): do not try to preview an ambiguous command (#18827)

feat: add preview functionality to user commands

2022-05-31T14:55:05Z

Adds a Lua-only `preview` flag to user commands which allows the command to be incrementally previewed like `:substitute` when 'inccommand' is set.
