dirstate.statwalk: explicitly test for ignored directories

This removes a hack where we appended '/' to a dirname so that:
- it would not appear on the "dc" dict
- it would always be matched by the match function

This was a contorted way of checking if the directory was matched by
some hgignore pattern, and it would still fail with some uses of
--include/--exclude patterns.

Things would still work fine if we removed the check altogether and
just appended things to "work" directly, but then we would end up
walking ignored directories too, which could be quite a bit of work.

This allows further simplification of the match function returned by
util._matcher, and fixes walking the working directory with a
--include pattern that matches only the end of a name.

MERCURIAL QUICK-START

Setting up Mercurial:

 Note: some distributions fails to include bits of distutils by
 default, you'll need python-dev to install. You'll also need a C
 compiler and a 3-way merge tool like merge, tkdiff, or kdiff3.

 First, unpack the source:

 $ tar xvzf mercurial-<ver>.tar.gz
 $ cd mercurial-<ver>

 When installing, change python to python2.3 or python2.4 if 2.2 is the
 default on your system.

 To install system-wide:

 $ python setup.py install --force

 To install in your home directory (~/bin and ~/lib, actually), run:

 $ python setup.py install --home=${HOME} --force
 $ export PYTHONPATH=${HOME}/lib/python  # (or lib64/ on some systems)
 $ export PATH=${HOME}/bin:$PATH         # add these to your .bashrc

 And finally:

 $ hg debuginstall                       # run some basic tests
 $ hg                                    # show help

 If you get complaints about missing modules, you probably haven't set
 PYTHONPATH correctly.

Setting up a Mercurial project:

 $ hg init project     # creates project directory
 $ cd project
                       # copy files in, edit them
 $ hg add              # add all unknown files
 $ hg commit           # commit all changes, edit changelog entry

 Mercurial will look for a file named .hgignore in the root of your
 repository which contains a set of regular expressions to ignore in
 file paths.

Branching and merging:

 $ hg clone project project-work    # create a new branch
 $ cd project-work
 $ <make changes>
 $ hg commit
 $ cd ../project
 $ hg pull ../project-work   # pull changesets from project-work
 $ hg merge                  # merge the new tip from project-work into
                             # our working directory
 $ hg commit                 # commit the result of the merge

Importing patches:

 Simple:
 $ patch < ../p/foo.patch
 $ hg commit -A

 Fast:
 $ cat ../p/patchlist | xargs hg import -p1 -b ../p

Exporting a patch:

 (make changes)
 $ hg commit
 $ hg export tip > foo.patch    # export latest change

Network support:

 # pull from the primary Mercurial repo
 foo$ hg clone http://selenic.com/hg/
 foo$ cd hg

 # make your current repo available via http://server:8000/
 foo$ hg serve

 # pushing and pulling changes to/from a remote repo with SSH
 foo$ hg push ssh://[e-mail]/my/repository
 foo$ hg pull ssh://[e-mail]//home/somebody/his/repository

 # merge changes from a remote machine (e.g. running 'hg serve')
 bar$ hg pull http://foo:8000/
 bar$ hg merge   # merge changes into your working directory
 bar$ hg commit  # commit merge in to your local repository

 # Set up a CGI server on your webserver
 foo$ cp hgweb.cgi ~/public_html/hg/index.cgi
 foo$ emacs ~/public_html/hg/index.cgi # adjust the defaults
