Re: pyhon mode indentation problem (note: its a more general problem)

Interestingly, if I change this definition like this, indentation
starts working!

(defun python-skip-comments/blanks (&optional backward)
  "Skip comments and blank lines.
BACKWARD non-nil means go backwards, otherwise go forwards.  Backslash is
treated as whitespace so that continued blank lines are skipped.
Doesn't move out of comments -- should be outside or at end of line."
  (with-syntax-table python-space-backslash-table
    (forward-comment (if backward
                         -1000
                       most-positive-fixnum))))


That is, I changed most-negative-fixnum to -1000.

I havent tested for which negative number the skip function stops
working, but this should be good info for those able to fix the
underlying problem..
