Subject: Fix "not" expressions consuming variable starting with not
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f86503d13a230d6bf699ba0222031e338dffd19d;p=thirdparty%2Fjinja.git

Fix "not" expressions consuming variable starting with not

The `not` expression should have a space between the word "not" and
the expression which is being negated. Otherwise it will incorrectly
pick up things like "nothing" as "not thing" because it technically
meets the criteria.
