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 openSUSE.
Please let us know if we missed some others.
Thanks,
Mark
bzgrep uses ${var//} which is a bashism.
Replace by calling sed so other POSIX shells work.
