Bug#682362: debuild: please leave $SHELL alone or provide a sane replacement

[Alexander Zangerl]

Package: devscripts
Version: 2.10.69+squeeze2
Severity: normal

by default debuild removes the $SHELL variable.

SHELL is most definitely in the POSIX set (as per
http://pubs.opengroup.org/onlinepubs/9699919799/),
and a missing $SHELL causes problems for anything that 
relies on POSIX and tries to find the most appropriate 
command processor via $SHELL.

please either add $SHELL to the variables that are passed through,
or (re)set it to /bin/sh.
