pycompat: stop setting LC_CTYPE unconditionally Changeset a25343d16ebe aimed to align how LC_CTYPE is initialized across Python versions. However, as Yuya Nishihara pointed out, it changes the behavior of some str methods on Python 2. Curses requires that LC_CTYPE is initialized correctly. Therefore LC_CTYPE is set while curses is used and reset afterwards. It shouldn’t be a problem that some str methods behave differently on Python 2 while curses is used. At least it’s not a regression compared to what was done before d2227d4c9e6b. This again breaks non-ASCII filenames passed to the Subversion bindings on Python 2. Since it didn’t work before a25343d16ebe, it’s however not really a regression. A separate patch will be sent.
