isn't this controlled by the syntax table? As you can modify the syntax
table, you can modify how such things work. I seem to remember seeing a bit
of elisp that did this to make the regexp easier to write when needing to
do re-search. from memory, I think it temporarily changed the newline
syntax entry in the local syntax table, performed the search and since this
was all done within a saved context, everything is restored afterwards. I
remember it because at the time I remember thinking "thats a neat little
trick to simplify the regexp"
