* src/tty.c (TTY_USAGE): Rename from TTY_FAILURE, since this is used only for usage failures. All uses changed. (TTY_TTYNAME_FAILURE): New constant. (main): Remove no-longer-needed assignment of ENOENT to errno. Make status-setting clearer too. Report an error if ttyname fails even though stdin is a terminal, instead of silently pretending that stdin is not a terminal. * tests/tty/tty.sh: Test for this issue. This should fix Bug#78244.
