tests: flatten repo structure in test-commit.t
Let's move to parent directory before `hg init` repos, since they don't need to
be nested. It makes amend/strip messages that include full path to the backup
bundle shorter, for instance.
Mercurial
=========
Mercurial is a fast, easy to use, distributed revision control tool
for software developers.
Basic install::
$ make # see install targets
$ make install # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg # see help
Running without installing::
$ make local # build for inplace usage
$ ./hg --version # should show the latest version
See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
