I think this is the same issue reported here: https://groups.google.com/d/topic/vim_dev/07qFhT34nEI/discussion Probably it is caused by the new regular expression engine introduced in 7.4. See :help new-regexp-engine and :help two-engines for more details. The new engine is designed in a way that backreferences are really difficult. In the thread I link above Bram calls it a "miracle" that they work at all. :help 'regexpengine' provides a possible workaround for you until this gets fixed. Try doing ":set regexpengine=1" to see if that fixes it for you temporarily until the problem is fixed. -- -- You received this message from the "vim_dev" maillist. Do not top-post!
