Escaped colon only seems to work inside a character class

At some point, % stopped working for me when pointing at an end.

Given:

if 1
  #
else
  #
end

Starting at the if and pressing % jumps to the else, again and it jumps to the end... but once there, it gets stuck. (And likewise for all other block forms.)

This seems to fix that.

TBH I haven't read through matchit.vim to work out whether this change should be necessary (or is just working around a bug therein, say), but at worst it seems a pretty safe accomodation.

Hmm, that's very strange, I can't seem to reproduce this locally. Your change doesn't really break it for me, so I guess it makes sense to merge it, provided it fixes an issue on your end and changes nothing on our end. I'm still a bit nervous about merging something that I don't fully understand.

Could you let me know what your current Vim version is? I'd like to see if it really is some matchit bug at a particular Vim runtime version.

cpoptions can affect backslash interpretation. I think the answer is to drop the backslash entirely. [\:] will match both : and \.

Sorry I forgot to come back to this earlier.

I just dug a bit more, and realised I was using an ancient version of matchit -- 1.9, which predates the embarrassingly-relevant changes in 1.10.

I think I'll just close this now. 😅
