Fix word-counting script

Magit uses --literal-pathspecs when  committing, so ls-files failed to
expand '*.md' in the word-counting script.

For a  wild ride, I  recommend going through  Git's get_global_magic()
function in pathspec.c, which juggles with…

- GIT_FOO_PATHSPECS environment variables;
- --foo-pathspecs CLI arguments;
- ":(foo)" magic suffixes;

… where foo can be "literal", "glob", "noglob", or "icase".
