I became annoyed at how, when pressing M-Q (fill-paragraph) while in a
block like this:
#+CAPTION: This is a really long caption that I need
#+CAPTION: to describe my table in excruciating and unnecessary detail
Org takes no account of the #+ directives and simply smooshes all the
lines together like this:
#+CAPTION: This is a really long caption that I need +CAPTION: to describe my
#table in excruciating and unnecessary detail
So I wrote the following function. I have it bound to M-q in org-mode.
Its behaviour:
1. It wraps a series of #+CAPTION lines as if the caption directives are
not there -- ie it turns the above example into:
#+CAPTION: This is a really long caption that I need to describe my table in
#+CAPTION: excruciating and unnecessary detail
2. It ignores other #+XXX: directives, ie no filling is performed.
3. In every other context it behaves as 'fill-paragraph'.
