[Bug-AUCTeX] Funny paragraph fillling behaviour

[Florian Liekweg]

Hi, All,

I'm seeing some funny behaviour when typing M-q on a LaTeX
paragraph (or calling M-x LaTeX-fill-paragraph or typing
C-c C-q C-p):  LaTeX commands that end in '{}' and some
(but not all) inline equations are made the end of the line,
although the line could be longer.  Typing fresh text using
auto-fill-mode yields the desired result, but M-q or C-c C-q C-p
messes it up.  Two examples, both recreated in a freshly found
LaTeX-file:

--- #1: typed using auto-fill-mode yields: ----
This paragraph contains a \LaTeX{} command.  It is so long that it
spans over multiple lines.

--- hitting M-q with point before the first letter yields: ----
This paragraph contains a \LaTeX{}
command.  It is so long that it spans over multiple lines.

--- #2: typed using auto-fill-mode yields: ----
This paragraph contains a silly, dumb, short equation: $(a =
\subseteq)$ which is totally ridiculious.  It is also long enough to
span more than a single line.

--- hitting M-q with point before the first letter yields: ----
This paragraph contains a silly, dumb, short equation: $(a =
\subseteq)$
which is totally ridiculious.  It is also long enough to span more
than a single line.

--- end examples ---

Clearly, the line doesn't have to be broken after either '\LaTeX{}'
or '\subseteq)$'.

Note that I wouldn't mind M-q changing the text even when used on
a paragraph freshly typed using auto-fill-mode, but the indentation
that M-q produces in the examples above seems to be just wrong.

Cheers,
Florian
