Strange errors on :Linediff

[vladimiroff]

This happens on every second :Linediff, right before vimdiff opening.

This %04v][%p%%]\ [%L\ lines] is part of the statusline definition in my vimrc file.

Should be alright in the latest master. The problem was in the \| you had in your statusline. This was being executed like this:

exe "setlocal statusline=" . escape(statusline, ' ')

The fix was adding the pipe in the escape list.

I think there was a reasonable way to do let &statusline = "..." in vim and have it active only in the current buffer, but I can't really remember how. This would also solve the problem, and wouldn't need escaping.

[arecarn]

would setlocal be what you are looking for?

[xaizek]

@arecarn, 'setlocal' can't handle expressions. I think @AndrewRadev couldn't remember this syntax:

:let &l:{option-name} = {expr1}

From :help :let-&:

Like above, but only set the local value of an option (if there is one).  Works like :setlocal.

[AndrewRadev]

Yes, that was the syntax I was looking for :). Thanks, @xaizek, @arecarn, I've pushed a commit that uses &l:statusline instead.

Cool! I'm error free now.
