Log Message:
Update to 2.1. From the changelog:

- lots of fixes to get the thing working sufficienly for cvs2git
- main features
  - optionally detect and display ancestor branch information for
    new detected branches
  - never allow more than one revision of a file to be in a single
    patchset (this may disturb the patchset numbers for historical
    data :-(
  - use file revisions to help sort, so that initial imports
    won't be listed as patchset 1, with patchset 2 as the actual
    creation of the files.
  - reports log times in localtime (use TZ to override)
- many downstream patches from Debian, special thanks to Marcus
  Crafter for maintaining.  From the Debian changelog:
   - patch from Kim Hansen to fix time calculation bug
   - documentation patch from J. Bruce Fields
   - directory name handling patch from David Kilzer
   - others I'm not sure of, I'd happily update the credit here
