Thanks.

The ones in contrib/examples used to be part of git and they were meant to
get their shebang "#!/bin/sh" line replaced by the toplevel Makefile to
whatever shell suitable on the platform.  As you already know, /bin/sh on
Solaris is non-POSIX and we recommend people to use a POSIX compilant
shell.  The current Makefile suggests /bin/bash on Solaris, but either ksh
or /usr/xpg[46]/bin/sh should work.

So a NAK on contrib/examples/ part.

And replacing /bin/sh with /bin/bash for everybody is _wrong_, as bash is
not the only POSIX compliant shell.

Some of the scripts in contrib/ may be using bash-specific construct, but
I think they are already marked with "#!/bin/bash" on their first lines.
If there are some that use bash-ism without "#!/bin/bash", we should first
try to see if we can reasonably rewrite them to avoid bash-ism, and mark
them as bash scripts if we can't.  I wounld't be so surprised if there are
some, but what I sampled randomly while writing this response were pure
POSIX as far as I can tell.
