           Summary: revset: or-joined
                    rangeset(":")/ancestorspec("~")/parentspec("^") may
                    unexpected result
          Severity: bug
    Classification: Unclassified
                OS: All
          Reporter: foozy at lares.dti.ne.jp
          Hardware: All
            Status: UNCONFIRMED
           Version: 2.5-rc
         Component: Mercurial
           Product: Mercurial

or-joined rangeset(":")/ancestorspec("~")/parentspec("^") revset
expressions may cause unexpected result like below:

  - "^"/parentspec():
    "R or R^1" is not equal to "R^1 or R". the former returns only "R".

  - "~"/ancestorspec():
    "R or R~1" is not equal to "R~1 or R". the former returns only "R".

  - ":"/rangeset():
    "10 or (10 or 15):" is not equal to "(10 or 15): or 10". the
    former returns only 15 or grater.

The latter of or-joined expressions are evaluated incorrectly,
because predicates above don't take care about subset narrowing
by orset("or").
