Control: Tags -1 patch 

Hi,

I can confirm that the problem with modelsim error parsing in VHDL mode is still there
in Ubuntu 14.04 with Emacs version 24.3.1 and vhdl-mode.el from the current gnu emacs
repository and also the original ubuntu vhdl-mode.elc version 3.33.28. 

I fixed the problem by modifying vhdl-mode.el file from the current repository. The patch is attached. 
By the way, the upstream link:

http://www.iis.ee.ethz.ch/~zimmi

is a dead link today. Attached are two pictures showing emacs before and after the fix and the patch of vhdl-mode.el.
