There is an overlapping issue from 2010: "curses.ascii.isblank() function is
broken. It confuses backspace (BS 0x08) with tab (0x09)"
http://bugs.python.org/issue9770
Your patch fixes it too (it should be closed). Note: the patch does not pass
tests from Lib/test/test_curses_ascii.py attached to issue9770 (even if the
code: `if char_class_name in ('cntrl', 'punct') test =
unittest.expectedFailure(test)` is removed) e.g., iscntrl(-1) should be False
but it returns True:
$ ./python
>>> import curses.ascii
>>> curses.ascii.iscntrl(-1) #XXX expected False
True
If we ignore negative ints then isblank, ispunct, iscntrl provided in the
curses_ascii.patch are ok.
