yesno behaves differently in a corner case depending on ENABLE_NLS. With an input of "y" followed by an EOF the input is considered to be "no", because the last character is replaced with '\0'. It was assumed that there is a newline, which doesn't have to be true. If ENABLE_NLS is not set, getchar() reads y and accepts it as "yes", looping through more getchar() calls until reaching newline or EOF. * lib/yesno.c (yesno): Check for EOL before replacing. * tests/test-yesno.sh: Add a test case (test along with gettext).
