Subject: Fix handling of tests which check constants
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=23a145dc2d7cfdd73c4c7022e0d620bfcd27e8fb;p=thirdparty%2Fjinja.git

Fix handling of tests which check constants

Because of how the parser works, it does not differentiate between
constants and function names, so this needs to convert it back.
