Hi,

is anyone using octave-mode in GNU Emacs 20.4 to run octave?  I've
found a slight problem with it, and it would be nice if someone could
verify/dismiss it.

It seems the inferior octave process doesn't like receiving a line of
Octave code that has a comment on the same line created using `M-;'
(octave-indent-for-comment).

e.g. take the following line:
pwd;				# print current directory.
where after the semicolon there are just four TAB characters up to the #.

If I do `C-c i l' (octave-send-line) on that line, I get the following
in the inferior octave buffer:

----------------------------------------------------------------------
octave.bin> pwd;				# print current directory.

Display all 900 possibilities? (y or n)
EDITOR                           int2str
... lots of possibilities deleted ...
parse error:

>>> pwd;print current directory.
                     ^

octave.bin> 
----------------------------------------------------------------------

So, it looks like the TABs before the comment are being interpreted as
completion requests.  

For now, I have a workaround solution within octave-send-region which
solves this problem (it just turns tabs into spaces before sending the
string to the inferior process).  If other people get this problem, I
can send that fix.  However, it may be a problem with other parts of
Emacs, so I think this bug was just introduced in Emacs 20.4.  (I
think this problem didn't occur in Emacs 20.3).

I'm running octave precompiled binary 2.0.13 if that makes any difference.

Cheers, Stephen
