run-tests: fixes the number of tests ran when '--retest' is enabled

This patch fixes a regression recently introduced by a refactoring. (see
92a6b16c9186 and about 200 previous changesets from Gregory Szorc)

While retesting, that is when '--retest' is enabled, only failure tests run
and others either skipped or ignored.

During retesting, "result.testsRun" holds the count of failure test that has
run. But as while printing output, we have subtracted the skipped and ignored
count from "result.testsRun". Therefore, to make the count remain
the same, we need to add skipped and ignored count before printing.

'''browse the repository in a graphical way

The hgk extension allows browsing the history of a repository in a
graphical way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk is not
distributed with Mercurial.)

hgk consists of two parts: a Tcl script that does the displaying and
querying of information, and an extension to Mercurial named hgk.py,
which provides hooks for hgk to get information. hgk can be found in
the contrib directory, and the extension is shipped in the hgext
repository, and needs to be enabled.

The :hg:`view` command will launch the hgk Tcl script. For this command
to work, hgk must be in your search path. Alternately, you can specify
the path to hgk in your configuration file::

  [hgk]
  path=/location/of/hgk

hgk can make use of the extdiff extension to visualize revisions.
Assuming you had already configured extdiff vdiff command, just add::

  [hgk]
  vdiff=vdiff

Revisions context menu will now display additional entries to fire
vdiff on hovered and selected revisions.
