bug#18622: Syntax highlighting in bat-mode

[Arni Magnusson]

There appears to be a bug in the syntax highlighting `bat-mode' (Emacs 
pretest 24.3.94). In the following lines, the word FOO should be 
highlighted:

  call FOO
  set FOO=42

I was able to get the desired syntax highlighting by moving one underscore 
within line 81 of bat-mode.el:

  \\<_  to  \\_<

and a similar change in line 85.

Cheers,

Arni
