I am testing Emacs CVS on Windows XP (fetched from the
nqemacs-project) and get errors in visual-basic-mode that I
did not get in 21.3. I have turned on debug-on-error and the
problem is with the following code:
(looking-at "^.*\\_[ ]*$")
If you evaluate the above you will get the error mentioned
in the subject line.
Is this a bug in Emacs or in visual-basic-mode.el? I know a
bit of regexp myself and the example above seems valid to me.

I solved my problem temporarily by changing the expression
to this:
(defconst visual-basic-continuation-regexp "^.*_[ \t]*$")
That extra backslash did not seem to make sense.
But still, is it really invalid?

\_ (backslash-underscore ) is not a defined regexp construct. In the
past it was treated as a 2-character sequence; apparently now that
should be represented as "\\\\_".

So, is it a bug or a feature?
