print_buffer: optimize & shrink
Applying a little creative format string allows us to shrink the initial data read & display loop by only calling printf once. Re-using the local data buffer to generate the string we want to display then allows us to output everything with just one printf call instead of multiple calls to the putc function. The local stack buffer needs increasing by 1 byte, but the resulting code shrink and speed up is worth it I think. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
