* stream.c (vformat): Fix bug in ~x format directive for printing
integers in hex. When we use the printf's %x conversion specifiers for
fixnums, we get incorrect results when the values are negative, because
the argument is actually treated as an unsigned integer.
The end result is that (format t "~x" -1) produces FFFFFFFF
rather than -1. Also, merged together mindless code duplication.
