commit: add option to amend the working dir parent
The --amend flag can be used to amend the parent of the working directory
with a new commit that contains the changes in the parent in addition to
those currently reported by "hg status", if there are any. The old commit
is stored in a backup bundle in ".hg/strip-backup"(see "hg help bundle"
and "hg help unbundle" on how to restore it).
Message, user and date are taken from the amended commit unless specified.
When a message isn't specified on the command line, the editor will open
with the message of the amended commit.
It is not possible to amend public changesets (see "hg help phases") or
changesets that have children.
Behind the scenes, first commit the update (if there is one) as a regular
child of the current parent. Then create a new commit on the parent's
parent with the updated contents. Then change the working copy parent
to this new combined changeset. Finally, strip the amended commit and
update commit created in the beginning.
An alternative (cleaner?) approach of doing this is suggested here:

It is currently not possible to amend merge commits or recursively,
this can be added at a later time.
journal: use tryread helper to backup files (
issue3375)
opener: introduce tryread helper
This makes it easier to follow the common pattern "read a file or give
an empty string if it's missing".
revset: make matching() work on python 2.4
tuple.index() was apparently added to python 2.6:
http://bugs.python.org/
issue1696444
Also remove a trailing comma to make check-code.py happy.
revset: use list instead of tuple for compatibility with python before 2.6
'string elements'.split() instead of explicitly typing a list of strings is
used. This is done in other parts of Mercurial code, too.
archive: make it work with svn subrepos (
issue3308)
- _svncommand() in files() returns a tuple since
0ae98cd2a83f not a string.
- _svncommand() in filedata() returns a tuple not a string.
- "svn list" returns files but also directories.
- "svn list" is not recursive by default.
I have no idea what happens to svn:externals possibly embedded in the svn
subrepository.
largefiles: hide .hglf/ prefix for largefiles in hgweb
This makes the manifest view in hgweb match what you see in the
working copy and what you get when you download an archive in hgweb.
hgweb: add hook for remapping repository path into virtual paths
Extensions such as largefiles can use this to remap files so they
appear in the same location as they do in the user's working copy.
