Rewrite log command.  New version is faster and more featureful.
The original implementation of log walked backwards through history,
which had terrible behaviour.  It took several minutes to view
complete kernel change history on a fast machine, for example.
The rewrite uses a windowed approach to walk hunks of history
forwards, while still giving results in reverse order.  This reduces
run time from five minutes to five seconds on my system.
In addition, the rewrite uses our normal name handling mechanisms, so
you can run a command like "hg log net/ipv4/**.c" and get a useful
answer.  It optimises for three different cases (no arguments, only
files, and anything goes), so it performs well in all circumstances
I've tested.

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>

 To install system-wide:

 $ python setup.py install   # change python to python2.3 if 2.2 is default

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

 $ python2.3 setup.py install --home=~
 $ export PYTHONPATH=${HOME}/lib/python  # (or lib64/ on some systems)
 $ export PATH=${HOME}/bin:$PATH         # add these to your .bashrc

 And finally:

 $ hg                                    # test installation, show help

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

Setting up a Mercurial project:

 $ cd project/
 $ hg init         # creates .hg
 $ hg addremove    # add all unknown files and remove all missing 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 linux linux-work    # create a new branch
 $ cd linux-work
 $ <make changes>
 $ hg commit
 $ cd ../linux
 $ hg pull ../linux-work     # pull changesets from linux-work
 $ hg update -m              # merge the new tip from linux-work into
                             # our working directory
 $ hg commit                 # commit the result of the merge

Importing patches:

 Fast:
 $ patch < ../p/foo.patch
 $ hg addremove
 $ hg commit

 Faster:
 $ patch < ../p/foo.patch
 $ hg commit `lsdiff -p1 ../p/foo.patch`

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

Exporting a patch:

 (make changes)
 $ hg commit
 $ hg tip
 28237:747a537bd090880c29eae861df4d81b245aa0190
 $ hg export 28237 > foo.patch    # export changeset 28237

Network support:

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

 # export your current repo via HTTP with browsable interface
 foo$ hg serve -n "My repo" -p 80
 
 # pushing changes to a remote repo with SSH
 foo$ hg push ssh://[e-mail]/~/hg/

 # merge changes from a remote machine
 bar$ hg pull http://foo/
 bar$ hg update -m        # merge changes into your working directory

 # 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
