[gedit-list] text file highlighted as VHDL

["Mikel Ward" <mikel mikelward com>]

I made a text file using ----- on a blank line as a header.

gedit decided it was a VHDL file and started coloring words like "or".

Can this be made a little more robust?

The file's extension is .txt, and Nautilus shows its type as plain
text document.
