commit: add ui.allowemptycommit config option
This adds a config flag that enables a user to make empty commits.
This is useful in a number of cases.
For instance, automation that creates release branches via
bookmarks may want to make empty commits to that release bookmark so that it
can't be fast-forwarded and so it can record information about the release
bookmark's creation. This is already possible with named branches, so making it
possible for bookmarks makes sense.
Another case we've wanted it is for mirroring repositories into Mercurial. We
have automation that syncs commits into hg by running things from the command
line. The ability to produce empty commits is useful for syncing unusual commits
from other VCS's.
In general, allowing the user to create the DAG as they see fit seems useful,
and when I mentioned this in IRC more than one person piped up and said they
were already hacking around this limitation by using mq, import, and
commit-dummy-change-then-amend-the-content-away style solutions.

Command Elements """""""""""""""" files... indicates one or more filename or relative path filenames; see `File Name Patterns`_ for information on pattern matching path indicates a path on the local machine revision indicates a changeset which can be specified as a changeset revision number, a tag, or a unique substring of the changeset hash value repository path either the pathname of a local repository or the URI of a remote repository. .. include:: hg.1.gendoc.txt Files """"" ``/etc/mercurial/hgrc``, ``$HOME/.hgrc``, ``.hg/hgrc`` This file contains defaults and configuration. Values in ``.hg/hgrc`` override those in ``$HOME/.hgrc``, and these override settings made in the global ``/etc/mercurial/hgrc`` configuration. See |hgrc(5)|_ for details of the contents and format of these files. ``.hgignore`` This file contains regular expressions (one per line) that describe file names that should be ignored by **hg**. For details, see |hgignore(5)|_. ``.hgsub`` This file defines the locations of all subrepositories, and tells where the subrepository checkouts came from. For details, see :hg:`help subrepos`. ``.hgsubstate`` This file is where Mercurial stores all nested repository states. *NB: This file should not be edited manually.* ``.hgtags`` This file contains changeset hash values and text tag names (one of each separated by spaces) that correspond to tagged versions of the repository contents. The file content is encoded using UTF-8. ``.hg/last-message.txt`` This file is used by :hg:`commit` to store a backup of the commit message in case the commit fails. ``.hg/localtags`` This file can be used to define local tags which are not shared among repositories. The file format is the same as for ``.hgtags``, but it is encoded using the local system encoding. Some commands (e.g. revert) produce backup files ending in ``.orig``, if the ``.orig`` file already exists and is not tracked by Mercurial, it will be overwritten.
