[Bug-AUCTeX] LaTeX-fill-break-at-separators with '$' mathmode problem

[Jaap Eldering]

Hi,

I'm using AUCTeX 11.86 with emacs 23.2.1 and I have
LaTeX-fill-break-at-separators set to (\\\( \\\) \\\[ \\\] "$").

This nicely breaks outside inline $$-math almost always, but sometimes
I notice that it does break the inline math. Just now I seem to have
found the specific case where it goes wrong.

The line below (note that it contains 73 characters, exactly the final
comma surpasses the 72 character line limit)

would need to be of infinite size to contain $x'(t)$ for all $t \in I$,

is broken as

would need to be of infinite size to contain $x'(t)$ for all $t \in
I$,

If I add one more character at the beginning of the line, or in the
mathmode and delete the comma, the complete inline statement
'$t \in I$' is correctly put onto the next line.

Just a minor issue, but it would be nice if this could be fixed.

Best,
Jaap
