annotate tests/identify.py @ 13:1ea479d26fce tip

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Make sure shifting phase and add bypass.py. - shifting phase is started after entering SHIFT state Transition from CAP to SHIFT does not induce shifting. - shifting phase is stoped after leaving SHIFT state. Transition from SHIFT to EXIT1 also induce a bit of shifting.
