patterns to match and the number of files to keep.  (Keeps the most
recently-modified distribution files matching each pattern.)

* Added "saveopts" command that saves all command-line options for the
current invocation to the local, global, or per-user configuration file.
Useful for setting defaults without having to hand-edit a configuration
file.

* Added a "setopt" command that sets a single option in a specified
distutils configuration file.
