This test does something broadly similar to :-

arg="some ...
... very ...
... long string ...
"

if test -z "$arg"
then
    ....
else
    echo "$arg" > ${TESTDIR}/dotest.tmp
    if $EXPR "`cat ${TESTDIR}/dotest.tmp`" : \
      "$arg"${ENDANCHOR} >/dev/null; then
        ....
     fi
fi


So, the expr command is no the first usage of the very long string,
but the expr command does include a few characters more than the
actual argument.   

Sadly, the only way I can think of to make this test work on a vanilla
HPUX system is to carge up the output with sed(1) and match it in
pieces, which is nontrivial.  The only way I can think of to do this
otherwise is to make a program which implements variant on expr's ":"
operator, but reads the expression from a file (thus getting round
command-length limits).


FWIW, I had a look at sanity.sh just now and noticed a typo.  This
version of sanity.sh is something I checked out of CVS some time back,
so the line numbers are likely to be off.
