Depending on the number if namespaces returned, it might be easier to convert
this to the following:

    my @tracked_namespaces = map {
    	chomp; s/_/ /g; $_;
    } split(/[ \n]/, run_git("config --get-all remote.${remotename}.namespaces"));

This would, once again, avoid creating @tracked_namespaces, and iterating over
it.

Note that this isn't about trying to 'golf' this; it's a performance
consideration.

Kindly,
