mergetools: don't let meld open all changed files on startup
In meld 3.16, a multi-file change with option '-a' results in
an overview list being opened.
In meld 3.20, a multi-file change with option '-a' results in
an overview list AND every changed file being opened.
Simply removing '-a' seems to work fine for both cases
and also behaves the same as before for single-file changes.
As per the release notes, this is due to the following change
in meld 3.19.0:
"Make the --auto-compare command line flag work again (Kai Willadsen)"

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.
Notes for packagers
===================
Mercurial ships a copy of the python-zstandard sources. This is used to
provide support for zstd compression and decompression functionality. The
module is not intended to be replaced by the plain python-zstandard nor
is it intended to use a system zstd library. Patches can result in hard
to diagnose errors and are explicitly discouraged as unsupported
configuration.
