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.
