Blocked revisions 87324 via svnmerge

The risk of breakage (since the tests aren't backported) seems higher
than the benefit for a point release, since this is not a semantic
change.

  #10719: restore messages generated on invalid compileall args

  Before the introduction of filename arguments to compileall it gave semi useful
  messages about not being able to 'list' names that weren't valid directories.
  This fix restores that behavior.  In addition to the test for this case, the
  patch also adds a test for the default behavior of compileall when no arguments
  are provided, and fixes a bug in one of the previously added tests.
