+ " Description: This command escapes the backslash and double quotes in a
+ " 	search pattern the correct number of times so it can be used in the :grep
+ " 	command. This command is meant to be used as:
+ " 	exec "silent! grep '".Tex_EscapeForGrep(pattern)."' file"
+ " 	NOTE: The pattern in the grep command should _always_ be enclosed in
+ " 	      single quotes (not double quotes) for robust performance.
