patch 9.1.0150: Several minor 'winfixbuf' issues Commit: https://github.com/vim/vim/commit/4bb505e28cac0389561fff78d8bbe0319c2bcf2f Author: Sean Dewar <6256228+seandewar@users.noreply.github.com> Date: Tue Mar 5 20:39:07 2024 +0100 patch 9.1.0150: Several minor 'winfixbuf' issues Problem: several minor 'winfixbuf' issues exist, mostly relating to the quickfix list Solution: address them and adjust tests. Retab and reflow a few things too. (Sean Dewar) Things touched include: - Replace the semsgs with gettext'd emsgs. - Handle window switching in ex_listdo properly, so curbuf and curwin are kept in-sync and trigger autocommands; handle those properly. - Don't change the list entry index in qf_jump_edit_buffer if we fail due to 'wfb' (achieved by returning FAIL; QF_ABORT should only be used if the list was changed). - Make qf_jump_edit_buffer actually switch to prevwin when using `:cXX` commands **outside** of the list window if 'wfb' is set in curwin. Handle autocommands properly in case they mess with the list. NOTE: previously, it seemed to split if 'wfb' was set, but do nothing and fail if prevwin is *valid*. This behaviour seemed strange, and maybe unintentional? Now it aligns more with what's described for the `:cXX` commands in the original PR description when used outside a list window, I think. - In both functions, only consider prevwin if 'wfb' isn't set for it; fallback to splitting otherwise. - Use win_split to split. Not sure if there was a specific reason for using ex_splitview. win_split is simpler and respects modifiers like :vertical that may have been used. Plus, its return value can be checked for setting opened_window in qf code (technically win_split_ins autocmds could immediately close it or change windows, in which the qf code might close some other window on failure; it's already the case elsewhere, though). closes: #14142 Signed-off-by: Sean Dewar <6256228+seandewar@users.noreply.github.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
