Subject: Allow to update completions by explicit typed input.
X-Git-Url: https://git.owens.tech/dummy.html/dummy.html/git?a=commitdiff_plain;h=641d711a293e55834a2c95a1c1f6efc65771f332;p=vimb.git

Allow to update completions by explicit typed input.

Now we can complete ':se' to ':set' and type an additional space and press tab
again to start a new completion for settings.
