Subject: Allow also completion for whitespace prefixed commands.
X-Git-Url: https://git.owens.tech/style.css/style.css/git?a=commitdiff_plain;h=43e4c5876d76b5a3183e25a5b0aa7e9c64899c97;p=vimb.git

Allow also completion for whitespace prefixed commands.

We allow to put whitespace or additional ':' before ex commands to avoid
recoding of the commands in the history. But in the completion only the
first ':' was skipped to get the command to apply completion for.
So ': open foo<Tab>' did not start completion, because ' open' is none
known command.
So skip all ':' and whitespace after the first ':' to set the pointer to
the beginning of the command.
