annotate testharness/tests/end2end.rs @ 171:e27c5c667a5a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Create full new types for return code and flags, separate end to end. This plumbs the ReturnCode and RawFlags types through the places where we call into or are called from PAM. Also adds Sun documentation to the project.
