Cut splits by equals sign and takes the second field. This ignores path
contents after a second equals sign. Currently this prevents the
installation on NixOS as the nix store path automatically contains a
"=".
This PR instead selects all but the first field and equals sign, leaving
the passed paths as intended.
Fixes#738 by changing the git config autocrlf test to check for what we do not want to see "false".
Instead of trying to convert the output of git config autocrlf to binary, which will not always work as "input" is also a valid value in addition to true and false, we check for the value false and exit if it is found.
