Bug#1078095: libeccodes-tools: please drop ksh and alternatives

[Chris Hofstaedtler <zeha@debian.org>]

Package: libeccodes-tools
Version: 2.36.1-1
X-Debbugs-CC: helmut@subdivi.de, debian-release@lists.debian.org

Hi,

libeccodes-tools is a key package, as such it pulls in its
dependencies into the key package set.

Currently it pulls mksh and possibly the listed alternatives pdksh |
zsh | ksh into the key package set.

>From what I can tell, only /usr/bin/bufr_compare_dir wants /bin/ksh,
and it looks like it would work unmodified with /bin/bash.

Please patch /usr/bin/bufr_compare_dir to specify #!/bin/bash and
drop the Depends: mksh | pdksh | zsh | ksh.

I'll also note that zsh doesn't actually provide /bin/ksh.

Thanks,
Chris
