Vim hangs with matchadd('...', '\%78v') and nowrap on large/long lines #310

What steps will reproduce the problem?

1. wget 
https://gist.githubusercontent.com/blueyed/b098ff662b2963621ec0/raw/a6f5a88f43c3
f55a48bf89ddcad08c86ed2e67c9/test.diff
2. vim -u NONE -N test.diff
3. :set nowrap
3. :call matchadd('ColorColumn', '\%78v', 100)

What is the expected output? What do you see instead?

The virtual column 78 should get highlighted.

Instead, Vim hangs and has to be killed with signal 9.

What version of the product are you using? On what operating system?

7.4.560 (hg)

Here is a patch, that mitigates the problem, by preventing matches impossible 
matches.

Thanks!

`:set re=2` did not appear to help, but the patch improves the behaviour.

It still takes ~2 seconds though to add the match.

Sorry, I meant re=1 as this is actually the old engine. Can you test with that 
one?
