So `if' can have zero or more whitespaces in front of it. And perhaps 
there might even be a tab character in front of it too. So you might 
want to consider matching

"^[ \t]*if\\|then\\|else\\|endif"

"^" will match the beginning of a line (as you know)
"[ \t]" will match a whitespace or a tab character
"*" will match zero or more of the thing before it.
So "[ \t]*" will match zero or more of either whitespace or tab and
"^[ \t]*if" will match `if' starting on a line with zero or more 
whitespace and / or tab characters in front of it.

HTH,
