I don't know if Emacs has its own way already to do this, but
in general ...

You could iterate the whole buffer line-by-line, and check
each line if it starts with '\' or not, e.g. with (looking-at
"\\\\"). When you find one "beg", start looking for where it
ends, and when you find that push (beg end) onto a list.

Then loop thru the list and do (fill-region beg end) for each
list pair item ...

PS. That sounds like fun, please post the code here :)
