Issue introduced by c3612b97e625ad0d70c6ba56d191bcb9a403f44c.
Example output before that commit (witch a random package using
fetchFromGitLab):
$ nix-instantiate --eval -A hiawatha.src.urls
[ "https://gitlab.com/api/v4/projects/hsleisink%2Fhiawatha/repository/archive.tar.gz?sha=v10.8.1" ]
After the commit:
$ nix-instantiate --eval -A hiawatha.src.urls
[ "https://gitlab.com/api/v4/projects/%2Fhsleisink%2Fhiawatha/repository/archive.tar.gz?sha=v10.8.1" ]
And with this very commit, which fixes the issue:
$ nix-instantiate --eval -A hiawatha.src.urls
[ "https://gitlab.com/api/v4/projects/hsleisink%2Fhiawatha/repository/archive.tar.gz?sha=v10.8.1" ]
The problem was that it has used optionalString in conjunction with "+",
so the optionalString only applied to the left-hand side of the +
operator.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.03
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
