[PATCH] fix bzdiff when TMPDIR contains spaces

[Mark Wielaard <mark@klomp.org>]

Hi,

bzip2 lost its domain and got a new home at https://sourceware.org/bzip2/
It also didn't see a release for a very long time. Causing various patches
used by distros to not have been integrated upstream. We are trying to
collect them all and do a new release.

The following patch comes from Debian.
Please let us know if we missed some others.

Thanks,

Mark

The bzdiff script doesn't contain enough quotes, so that it doesn't
work if the TMPDIR environment variable is defined and contains
spaces.
