The functions bb_perror_nomsg() and bb_perror_nomsg_and_die() are
used to print error messages where no specific information is
available. For example:
$ busybox mktemp -p /
mktemp: (null): Permission denied
mktemp(3) doesn't tell us the name of the file it tried to create.
However, printing '(null)' is a regression introduced by commit
6937487be (libbb: reduce the overhead of single parameter bb_error_msg()
calls). Restore the previous behaviour by reverting the changes to
the two functions mentioned:
$ busybox mktemp -p /
mktemp: Permission denied
function old new delta
bb_perror_nomsg_and_die 7 14 +7
bb_perror_nomsg 7 14 +7

libbb is BusyBox's utility library. All of this stuff used to be stuffed into
a single file named utility.c. When I split utility.c to create libbb, some of
the very oldest stuff ended up without their original copyright and licensing
information (which is now lost in the mists of time). If you see something
that you wrote that is mis-attributed, do let me know so we can fix that up.
