2.1.1 Revision options
----------------------

As to be expected in a revision control system, many options are of the
form ‘-FLAG[REV]’, where FLAG is a single letter (e.g., ‘r’).  If
ommitted, REV defaults to the latest revision on the default branch.  A
revision can be specified in many ways:

BR.N
     Straightforward dot-notation, where BR specifies the branch.

.N
     Like BR.N, using the default branch.

BR
     Like BR.N, using the a command-specific computation of N, given the
     current tip I.  For ci (Note: ci), N would be ‘I + 1’, while for
     other commands N would be simply I.

NAME
     This is the symbolic name of a revision, as assigned previously by
     a ‘ci -n’ or ‘ci -N’ command.

‘$’
     The command computes the effective revision by examining the values
     of keyword expansions in the working file.

For commands that accept a range of revisions, the syntax is generally
‘REV1:REV2’, i.e., two revisions (specified as described above)
separated by a colon.
