I think that's a good idea. Perhaps based on a standard format such as '# TODO 2014-01-01 Fix me' ?

Why put the date in the comment itself? Just ask source control when the line was introduced, and set a max age.

Interesting idea, but I'm not sure if that would be possible for all cases, for example what happens if the part of the line before the comment changed?

Fantastic idea and what I thought when I saw this post; I'm slightly surprised that nobody has produced a git one-liner to achieve this yet!
