crecord: re-enable reviewing a patch before comitting it
The "r" option for this feature was copied into Mercurial from
crecord, but the actual implementation never made it into hg until
now. It's a moderately useful feature that allows the user to edit the
patch in a text editor before comitting it for good.
This requires a test, so we must also enable a corresponding testing
'R' option that skips the confirmation dialogue. In addition, we also
need a help text for the editor when reviewing the final patch.
As for why this is a useful feature if we can already edit hunks in an
editor, I would like to offer the following points:
* editing hunks does not show the entire patch all at once
** furthermore, the hunk "tree" in the TUI has no root that could be
selected for edition
* it is helpful to be able to see the entire final patch for
confirmation
** within this view, the unselected hunks are hidden, which is
visusally cleaner
** this works as a final review of the complete result, which is
a bit more difficult to do conceptually via hunk editing
* this feature was already in crecord, so it was an oversight to
not bring it to core
* it works and is consistent with editing hunks
