This fix provide working --revision-range for ClearCase.
Notes:
To use revision range we must generate changeset before we run post-review
script. All revisions is split by ':' sign. Number of revisions must be
even. Diff is generated between two adjacent revisions.
Usage example:
post-review -d --server "http://reviews.reviewboard.org/" --revision-range
