You have run into the C Shell's "parser": ifs inside false ifs must
have whitespace after the word "if"; elsewhere, ifs may be separated
from their arguments by parentheses.  Thus

	if (anything_false)
		foo
		if(anything)
			bar
		endif
		echo oops
	endif

fails, while

	if (anything_false)
		foo
		if (anything)
			bar
		endif
		echo oops
	endif

succeeds.  The only difference is a single space.
