Retry au * * autocmd if in cmd line and it throws E1155

See issue #33
Code change discussed with @bruno-
thx,
-m

I added a redraw! if it threw, because without this nvim doesn't display anything until you exit the cmdline or esc.

@bruno- I think we need to re-think this. If I get into this situation by typing / too quickly then the autocmd never works and the retry loop just keeps retrying forever. For vim, not nvim I think.
Perhaps I can check v:vim_did_enter or something ? I will work on it today.
Until this is solved properly I think this change should be reverted, sorry.

Do we need to autocmd * here ? Or would CmdLineEnter,CmdLineChanged work ? It seems an autocmd is added and then in the delayed_checktime() the autocmd is removed ? Is that right ? Why that instead of just calling delayed_checktime() or just checktime inside a try/catch ?

The vim help shows -

:au[tocmd] [group] {event} {pat} [++once] [++nested] {cmd}
			Add {cmd} to the list of commands that Vim will
			execute automatically on {event} for a file matching
			{pat} |autocmd-patterns|. 
			Here {event} cannot be "*".  *E1155*

So for vim we cannot use autocmd * * ...
