Something which bugs me quite a lot is when there is an error code (which
tells you why something didn't work) and you have an error message, and
the error message doesn't bother printing the error code.
You might as well just print "Failed\n" and leave it at that, or md5sum
the error message and print the sum instead. :)
Knowing why something failed allows you to read the source, and find
possible reasons for the failure (which could come down to one reason)
and allows faster resolution of the problem.
