I am trying to put in another data structure to make line searching faster,
which must be maintained during every insert/delete operation. It looks
like interval tree is not something I should touch. It looks like all those
functions (e.g. scan_newline) in search.c and insert functions in insdel.c
are things I should take a deeper look at, does that sound right?
