texi2dvi is a bash script, not a Bourne shell script

[Prof Brian Ripley]

On Solaris 10, installed from the sources:

swift-9% texi2dvi --version
texi2dvi (GNU Texinfo 6.0) 6363

and any invocation gives

/usr/local/bin/texi2dvi: BSTINPUTS: not found

The head of the script is

#! /bin/sh
# texi2dvi --- produce DVI (or PDF) files from Texinfo (or (La)TeX) sources.
# $Id: texi2dvi 6363 2015-06-26 12:36:32Z gavin $

and /bin/sh is a Bourne shell derived from AT&T Unix.

Using --debug does not help me:

Error: compiling TeX file 'displaylist.tex' failed with message:
Running 'texi2dvi' on 'displaylist.tex' failed.

Changing to

#! /bin/bash

makes this work.
