Redmine

I propose removing the .hgignore file for the Mercurial repository.

The official Redmine repository is the Subversion repository hosted on https://svn.redmine.org/. In addition, an unofficial Git mirror repository is available at https://github.com/redmine/redmine.

In the past, a Mercurial mirror repository was also available on bitbucket.org. However, it became inaccessible no later than 2020, and no Mercurial mirror repository has existed since then.

The .hgignore file still exists in the source tree, but it is considered to be a remnant of the former Mercurial mirror repository. Mercurial is no longer used for Redmine development or distribution.

Although Mercurial is no longer used in the Redmine project, we still need to maintain and keep in sync three separate ignore configurations: the svn:ignore property, .gitignore, and .hgignore.

To reduce maintenance overhead and avoid giving the impression that Mercurial-based development or distribution is still supported, I would like to remove the .hgignore file.
