===============================
- No stdin for python calls from bash completion functions (488)
Prevents usage of stdin by (python) executables that are called
during completion generation. This prevents the completion locking up
the entire shell when the python script is broken i.e. it enters an
interactive mode (REPL) instead of generating the completions, as
expected.
- Localize shell variable REPLY to avoid overwriting users’ value
(489)
The variable REPLY is used by default by the ``read`` shell builtin
to store the return value, and like all bash/zsh variables, is scoped
globally. This change allows this variable to be used for other needs
by appropriately scoping its internal use by an argcomplete utility
function that uses ``read``.
