SF #558432: Prevent Annoying ' ' from readline (Holker Krekel).
readline in all python versions is configured
to append a 'space' character for a successful
completion. But for almost all python expressions
'space' is not wanted (see coding conventions PEP 8).
For example if you have a function 'longfunction'
and you type 'longf<TAB>' you get 'longfunction '
as a completion. note the unwanted space at the
end.
The patch fixes this behaviour by setting readline's
append_character to '\0' which means don't append
anything. This doesn't work with readline < 2.1
(AFAIK nowadays readline2.2 is in good use).
An alternative approach would be to make the
append_character
accessable from python so that modules like
the rlcompleter.py can set it to '\0'.
[Ed.: I think expecting readline >= 2.2 is fine. If a completer wants
another character they can append that to the keyword in the list.]
