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).
