I see; so as the font-lock mechanism is flexible enough to allow code
to be excuted for a match, it seems there should be no problem to use
special text-properties to locate the exact column of the match.

That is:

  (1) Use a process filter to translate escape sequences to text-properties

  (2) Use the normal font-lock-like matcher to locate each grep match-line

  (3) In the match-term, optionally look for the text-properties added in (1)
       to provide column information
