Merge trunk. Simplify handling of "w" option a little. check-in: f4d98b2b user: jan.nijtmans tags: diff-eolws
21:29
Add new --ignore-space-at-sol, -ignore-space-at-eol and -w options to "fossil diff" and "fossil stash diff" commands. Modify annotation/blame such that any change (eol-whitespace too) is considered a change, after ML request. check-in: e663d5e3 user: jan.nijtmans tags: trunk

  *  The [/reports] page now requires Read ("o") permissions. The "byweek"
     report now properly propagates the selected year through the event type
     filter links.
  *  The [/help/info | info command] now shows leaf status of the checkout.
  *  Add support for tunneling https through a http proxy (Ticket [e854101c4f]).
  *  Add option --empty to the "[/help?cmd=open | fossil open]" command.
  *  Enhanced [/help?cmd=/fileage|the fileage page] to support a glob parameter.
  *  Add --ignore-space-at-sol and --ignore-space-at-eol options to [/help?cmd=diff|fossil (g)diff],


     [/help?cmd=stash|fossil stash diff]. The option -w activates both of them.
  *  Add button "Ignore Whitespace" to /ci, /vdiff and /fdiff UI pages.


<h2>Changes For Version 1.28 (2014-01-27)</h2>
  *  Enhance [/help?cmd=/reports | /reports] to support event type filtering.
  *  When cloning a repository, the user name passed via the URL (if any)
     is now used as the default local admin user's name.
  *  Enhance the SSH transport mechanism so that it runs a single instance of
     the "fossil" executable on the remote side, obviating the need for a shell
