- shellcmd completion is VERY slow on both WSL and Windows, e.g. `term something` or `!something` might take ~10 seconds to show first results. Do not complete it there. - revert previous change to not complete on whitespace, do not complete on *empty* lines instead. closes: #18568 Signed-off-by: Maxim Kim <habamax@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
