fileset: add kind:pat operator ":" isn't taken as a symbol character but an infix operator so we can write e.g. "path:'foo bar'" as well as "'path:foo bar'". An invalid pattern kind is rejected in the former form as we know a kind is specified explicitly. The binding strength is copied from "x:y" range operator of revset. Perhaps it can be adjusted later if we want to parse "foo:bar()" as "(foo:bar)()", not "foo:(bar())". We can also add "kind:" postfix operator if we want. One possible confusion is that the scope of the leading "set:" vs "kind:pat" operator. The former is consumed by a matcher so applies to the whole fileset expression: $ hg files 'set:foo() or kind:bar or baz' ^^^^^^^^^^^^^^^^^^^^^^^^ Whereas the scope of kind:pat operator is narrow: $ hg files 'set:foo() or kind:bar or baz' ^^^
