Yet another edge-case: In the Org syntax definition a property
name is really delimited by a "colon-whitespace" sequence. This
takes out the ambiguity whether a property name is defined
non-greedily
:[^[:space:]]+?:
or greedily
:[^[:space:]]+:
I'm too lazy right now to think about the consequences, but I
hope this makes a difference only for really weird property
matches, like this:
:foo:=1+:bar:=2
This would be parsed non-greedily as
FOO == 1 && BAR == 2
or greedily as
FOO:=1+:BAR == 2
I'd go for non-greedily defined property names.
