[cedet-semantic] determining exuberant ctags version

[Mandar M. <ma...@is...>]

Hi,

I've recently started using a fresh install of Ubuntu 11.04. Most of my
emacs related files, including CEDET, reside in ~/.emacs.d, so these were
not changed by the upgrade. 

Even after installing exuberant ctags, CEDET was unable to recognise its
presence. The problem was traced to the following:

1. ctags --version prints:

   Exuberant Ctags 5.9~svn20110310, Copyright (C) 1996-2009 Darren Hiebert

2. The version number does not match the original regexp on line 144 of 
   cedet/semantic/ctags/semantic-ectag-util.el. I've changed this to:

   (if (re-search-forward "Exuberant Ctags \\([0-9.]+\\)[^0-9.]" nil t)

   This works for me. In some ways, this looks logical too -- match a
   sequence of digits and dots until you encounter something that is
   not a digit or dot. If you think this is all right, you could
   incorporate this into the trunk.

I'm sorry I can't provide a proper patch. I did this before my emacs was
properly setup, and I don't have the original against which to do a diff.

Best wishes,
Mandar.
