+ like curses.ACS_HLINE: the Python function addch(int) and addch(bytes) is now

+ even when msg isn't a str.
+

+ errors correctly. Patch by Serhiy Storchaka.
-- Issue #12776,#11839: call argparse type function (specified by add_argument)
- only once. Before, the type function was called twice in the case where the
- default was specified and the argument was given as well. This was
- especially problematic for the FileType type, as a default file would always
- be opened, even if a file argument was specified on the command line.
+- Issue #14846: importlib.FileFinder now handles the case where the
+ directory being searched is removed after a previous import attempt
