[erlang-patches] Fix searching for source files in cover:analyse_to_file/*

My mistake with the exports, I'd seen it as the functions being exported
twice but really it was different spellings of the functions: analyse with
an S vs analyze with a Z. It looks like analyse with the S are the
documented functions... however I better restore it, someone must be using
the Z versions.

I'll clean up the code as per you suggestions below and post an update.
