Subject: [PATCH] Add special consideration for rlcompleter. As a side effect
of initializing GNU readline, setlocale(LC_CTYPE, "") is called, which
changes the <ctype.h> macros to use the "default" locale (which isn't the
*initial* locale -- the initial locale is the "C" locale in which only ASCII
characters are printable). When the default locale is e.g. Latin-1, the
repr() of string objects can include 8-bit characters with the high bit set;
I believe this is due to the recent PRINT_MULTIBYTE_STRING changes to
stringobject.c. This in turn screws up test_pyexpat and test_rotor, which
depend on the repr() of 8-bit strings with high bit characters.
The solution (for now) is to force the LC_CTYPE locale to "C" after
importing rlcompleter. This is the locale required by the test suite
anyway.
