* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
(about 1400, 22%), this commit refactors all of those instances.
* pkgs: Fixing some links that were wrongfully unquoted in the previous
commit
* Fixed some instances
* tig: 2.2 -> 2.2.1
Also move to different project URLs, as requested in
https://github.com/jonas/tig/releases/tag/tig-2.2.1
* tig: fix fetching mechanism
Rework the dependencies to allow use of fetchFromGitHub.
This ensures that git is added as a run-time dependency of tig and
allows tig to find the git command even if git is not installed in the
user environment. Fixes#5741.
Since version 2.0, tig can use readline for history/completion support,
so add readline as a build input.
Increases closure size from 53 MiB to 54 MiB.
Copy the bash completion script that comes with tig to
$out/etc/bash_completion.d/.
Note: to enable bash completion in NixOS, set
environment.enableBashCompletion = true;
