Whitespace Sensitive Grammar

Description

X%AT%from < X^from-2

is invalid while

X%AT%from < X^from - 2

is ok.

Comments

I suspect that X^from-2 gets tokenized as X,^,from,-2

The proper solution to this would be to change RE_NUM (in scanner.l.m4) and introduce a unary minus operator in the appropriate places in parser.y.
