hg copy [OPTION]... [SOURCE]... DEST

mark files as copied for the next commit

aliases: cp

options:

 -I --include  include path in search
 -X --exclude  exclude path from search
 -A --after    record a copy after it has happened
 -f --force    replace destination if it exists
 -p --parents  append source path to dest
50 jbb at cloves /tmp/jbb_test > hg cp -p three ten
abort: with --parents, destination must be a directory

=================================

Sorry, that was probably a little long winded.  The main problems I have are:

1) If, during a remove, a directory tree becomes empty and the remove command was issued using that directory (eg. `hg remove three` above), I think that we should prune the empty directory tree as we do for updates.

2) It seemed to me that `hg cp -p` would work like `cp -R` and that it would create the new directory structure for me.
