gnupg is gnupg 2.2. gnupg1 is also gnupg 2.2, just with a few extra
symlinks in the bin directory. None of these packages need those
symlinks, and it's confusing for them to say they're depending on
"gnupg1", so switch their dep to plain "gnupg".
git-crypt won't work if git and git-crypt are not in PATH. This surfaced
after dbb8958. Test like this:
```
PATH= $(nix-build --no-out-link '<nixpkgs>' --attr git-crypt)/bin/git-crypt unlock
```
* 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
In line with the Nixpkgs manual.
A mechanical change, done with this command:
find pkgs -name "*.nix" | \
while read f; do \
sed -e 's/description\s*=\s*"\([a-z]\)/description = "\u\1/' -i "$f"; \
done
I manually skipped some:
* Descriptions starting with an abbreviation, a user name or package name
* Frequently generated expressions (haskell-packages.nix)
