Switch to new syntax for .hgignore files.
Here is the new syntax, in summary.
Trailing white space is dropped.
The escape character is "\".
Comments start with #.
Empty lines are skipped.
Lines can be of the following formats:
syntax: regexp # defaults following lines to non-rooted regexps
syntax: glob # defaults following lines to non-rooted globs
re:pattern # non-rooted regular expression
glob:pattern # non-rooted glob
pattern # pattern of the current default type
The default pattern type is regexp, which is completely backwards
compatible with the old hgignore syntax.
In the dirstate class, the ignore method has been reworked to be based
on the util.matcher function, by way of a new dirstate.hgignore
method.
hgweb: use ui:username rather than web:contact
This also removes the creation of .hg/hgrc with web:contact at init time.
Clamp negative rev numbers at zero.
Prior to this change, trying to run "hg log -r -50:" in a repo with
less than 50 changes caused an error. Now that we clamp at zero: no
more error.
Get all commands that operate on files to honour --verbose and --quiet.
Fix minor bug in remove command; the when-to-unlink logic was wonky.
Switch cat command to use walk code.
The old syntax of "hg cat FILE REV" is now obsolete.
Use "hg cat -r REV FILE" instead, as for all other commands.
Add rename/mv command.
This is the logical equivalent of copy and remove, and is in fact
implemented as such. It doesn't use the remove command directly.
Fix lots of exception-related problems.
These have been around since the Big Code Split.
Fix up copy command to behave more like regular "cp".
In addition to recording changes, copy now updates the working
directory.

Please try this:
Add support for cloning with hardlinks on windows.
In order to use hardlinks, the win32file module is needed, and this is
present in ActivePython. If it isn't present, or hardlinks are not supported
on the underlying filesystem, a regular copy is used.
When using hardlinks the biggest benefit is probably the saving in space,
but cloning can be much quicker. For example cloning the Xen tree
(non trivial) without an update goes from about 95s to 15s.
Unix-like platforms should be unaffected, although should be more tolerant on
filesystems that don't support hard links.
(tweaked by mpm to deal with new copyfiles function)
