config: do not ungetc EOF
When we are parsing a config value, if we see a carriage return, we fgetc the next character to see if it is a line feed (in which case we silently drop the CR). If it isn't, we then ungetc the character, and take the literal CR. But we never check whether we in fact got a character at all. If the config file ends in CR, we will get EOF here, and try to ungetc EOF. This works OK for a real stdio stream. The ungetc returns an error, and the next fgetc will then return EOF again. However, our custom buffer-based stream is not so fortunate. It happily rewinds the position of the stream by one character, ignoring the fact that we fed it EOF. The next fgetc call returns the final CR again, over and over, and we end up in an infinite loop. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
