The syntax is ${parameter:-word} (i.e. previously this used
"latestTag" instead of the actual value).
(Fixes a regression from #85278.)
Also: Even though getting the latest tag isn't really security critical
(as long as Git itself is secure against untrusted input), I'd prefer to
switch from the Git to the HTTPS protocol (for authentication of the
server and encryption + uses a standard port).
tig recently updated it's bash-completion making it depend on __git-complete from git.
Becase __git-complete is not automatically sourced tig bash completion fails.
Also this PR makes tig completion load on-demand.
init an unstable version since the tagged release wouldn't work on my
machine (infinite loop).
Practical tool to fetch several repositories at the same time, see their
status etc.
Disabled for darwin because of CI error "SIGILL: illegal instruction".
git-cinnabar calls into Mercurial as a library, so we make use the
same version of Python as Mercurial.
Support for Python 3 is an experimental feature in git-cinnabar, but
we unconditionally use it here because:
* Mercurial in Nixpkgs only supports Python 3.
* git-cinnabar touches a network, and for that purpose it's good to
use a version of Python that is going to get security updates.
