The current code already allows skipping directories, but the full path
must be given, e.g. "./.git" instead of just ".git", as "codespell ." is
the default.
Allow --skip to be used with relative directory names, too.
From discussion in GH#85, the executable was renamed to
codespell to preserve backward compatibility with how
the Makefile used to install the library.
