subrepo: avoids empty commit when .hgsubstate is dirty (issue2403)

This patch avoids empty commit when .hgsubstate is dirty. Empty commit
was caused by .hgsubstate being updated back to the state of the
working copy parent when committing, if a user had changed it manually
and not made any changes in subrepositories.

The subrepository state from the working copies parent is compared
with the state calculated as a result of trying to commit the
subrepositories. If the two states are the same, then return None
otherwise the commit is just done.

The line: "committing subrepository x" will be written if there is
nothing committed, but .hgsubstate is dirty for x subrepository.

#
# Keyword expansion hack against the grain of a DSCM
#
# There are many good reasons why this is not needed in a distributed
# SCM, still it may be useful in very small projects based on single
# files (like LaTeX packages), that are mostly addressed to an
# audience not running a version control system.
#
# For in-depth discussion refer to
# <http://mercurial.selenic.com/wiki/KeywordPlan>.
#
# Keyword expansion is based on Mercurial's changeset template mappings.
#
# Binary files are not touched.
#
# Files to act upon/ignore are specified in the [keyword] section.
# Customized keyword template mappings in the [keywordmaps] section.
#
# Run "hg help keyword" and "hg kwdemo" to get info on configuration.

'''expand keywords in tracked files

This extension expands RCS/CVS-like or self-customized $Keywords$ in
tracked text files selected by your configuration.

Keywords are only expanded in local repositories and not stored in the
change history. The mechanism can be regarded as a convenience for the
current user or for archive distribution.

Keywords expand to the changeset data pertaining to the latest change
relative to the working directory parent of each file.

Configuration is done in the [keyword], [keywordset] and [keywordmaps]
sections of hgrc files.

Example::

    [keyword]
    # expand keywords in every python file except those matching "x*"
    **.py =
    x*    = ignore

    [keywordset]
    # prefer svn- over cvs-like default keywordmaps
    svn = True

.. note::
   The more specific you are in your filename patterns the less you
   lose speed in huge repositories.

For [keywordmaps] template mapping and expansion demonstration and
control run :hg:`kwdemo`. See :hg:`help templates` for a list of
available templates and filters.

Three additional date template filters are provided::

    utcdate      "2006/09/18 15:13:13"
    svnutcdate   "2006-09-18 15:13:13Z"
    svnisodate   "2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"

The default template mappings (view with :hg:`kwdemo -d`) can be
replaced with customized keywords and templates. Again, run
:hg:`kwdemo` to control the results of your configuration changes.

Before changing/disabling active keywords, run :hg:`kwshrink` to avoid
the risk of inadvertently storing expanded keywords in the change
history.

To force expansion after enabling it, or a configuration change, run
:hg:`kwexpand`.

Expansions spanning more than one line and incremental expansions,
like CVS' $Log$, are not supported. A keyword template map "Log =
{desc}" expands to the first line of the changeset description.
