- Feature #934, supports 'reserved.lines' to indicate a multi-line prompt for
  use in conjunction with 'limit:page' (thanks to Robert Gill).
- Removed 'locale' from the taskrc.5 man page.
- Added verbosity token 'sync'.
- Fixed bug in size calculation for 'limit:page', but there is still one more.
- Corrected unit test limit.t given the above fix.
