Blocked revisions 87324 via svnmerge ........ r87324 | r.david.murray | 2010-12-16 14:08:51 -0500 (Thu, 16 Dec 2010) | 9 lines #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. ........
