This replaces git-clean.sh with builtin-clean.c, and moves
git-clean.sh to the examples.
This also introduces a change in behavior when removing directories
explicitly specified as a path. For example currently:
1. When dir has only untracked files, these two behave differently:
$ git clean -n dir
$ git clean -n dir/
the former says "Would not remove dir/", while the latter would say
"Would remove dir/untracked" for all paths under it, but not the
directory itself.
With -d, the former would stop refusing, however since the user
explicitly asked to remove the directory the -d is no longer required.
2. When there are more parameters:
$ git clean -n dir foo
$ git clean -n dir/ foo
both cases refuse to remove dir/ unless -d is specified. Once again
since both cases requested to remove dir the -d is no longer required.
Thanks to Johannes Schindelin for the conversion to using the
parse-options API.
