trace: correct variable name in write() error message
Our error message for write() always mentions GIT_TRACE, even though we may be writing for a different variable entirely. It's also not quite accurate to say "fd given by GIT_TRACE environment variable", as we may hit this error based on a filename the user put in the variable (we do complain and switch to stderr if the file cannot be opened, but it's still possible to hit a write() error on the descriptor later). So let's fix those things, and switch to our more usual "unable to do X: Y" format for the error. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
