Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
- Implemented D 2.0 additions. - Added keyword __traits, TOK.Traits and TraitsExpression. - Added ForeachRangeStatement, ConstType and InvariantType. - Fix: avoid infinite loop by calling nT() to skip storage class. - Fix: don't call nT() in parseVersionDeclaration.parseIdentOrInt().
