Subject: [PATCH] Remove the nagios-comments and nagios-string constants. Don't
 highlight comments and strings via keywords. Make keyword highlighting
 case-sensitive. Remove some comments from the main mode function. Added a
 syntax table. Enable syntax highlighting for comments and strings. Add
 comment-start and comment-end definitions.
