Ben Jackson	30eec0d93c	Fix variable substitution for multiple defaulted vars ... The problem was that the python regex engine is strictly left-to-right, so matching `[^}]|\\}` against \\}} meant that the `\\` was consumed by the left of the `|`. The solution is to just switch them around. Also add a way to run python tests from within vim, so we can actually test this stuff.	2021-02-06 20:55:24 +00:00
