curses: do not setlocale() at import time (issue5261)

setlocale() can break date formatting/parsing functions because they are
locale dependent. We should avoid doing setlocale() as possible.

This patch moves setlocale() just before curses.wrapper(), which function
is documented to "initialize curses." I don't know the details about the
curses initialization, but I *think* this would work as well.

Maybe we can extract a curses setup function later.

  $ hg ci -m first
  $ echo a > to-be-deleted
  $ hg ci -m second
  $ rm to-be-deleted
  $ hg diff -r 0

Same issue, different code path
