Hmm... here's an interesting data point. I had TTBOMK no active parsing
(KDevelop sitting idle for a while). Then I switched to a different git
branch (outside of KDevelop), followed immediately by doing a pull (so,
possibly, KDevelop started parsing the pre-pull files). I then opened a
file that I did not previously have open, and am seeing this issue.

Thus, at the least, I can say with some confidence that the problem
doesn't seem to depend on editing a file *in KDevelop*. There may be an
issue with a file being changed on disk, outside of KDevelop, while it
is being parsed.

A rough guess what may be happening:

- File changes on disk ("rev A").
- KDevelop starts to re-parse file.
- File changes on disk again ("rev B").
- KDevelop finishes parsing "rev A".
- User opens file in KDevelop.
- KDevelop highlights per "rev A", but file content is "rev B".

...although I was unsuccessful at trying to reproduce that intentionally.
