`combine-after-change-calls' won't combine anything when
`before-change-functions' is non-nil.

When you fill text you would have to (1) scan every line for occurrences
of these strings in `before-change-functions' and record these
occurrences somehow (maybe using markers), (2) apply the change for that
line, and (3) scan the line again for matching occurrences of these
strings in `after-change-functions' (and maybe release the markers).
All this in the presence of some LaTeX syntax specific math context
whose bounds you have to recalculate for every single change too.  And,
what's worse, all this is completely useless since filling shouldn't
affect fontification anyway.
