[PATCH] test install()

[Ilya Zakharevich <nospam-abuse@ilyaz.org>]

The branch of test which checks for failure of install() does not work
on OS/2.  I saw also reports that it does not work on AIX too.

I needed the following change to make it work on OS/2.  I have no idea
where this number 49 comes from...  (I also took an opportunity to fix
identation; the diff -pubw is

     pat=`${head}4 $file_diff|${tail}1|grep "112,122"`
     sys0190=`grep "^+ SYS0190\>" $file_diff`

    -if test $len -eq 51  -a  -n "$sys0190"; then
    -  len=49                       # more verbose error message on OS/2
    +  if test -n "$sys0190"; then
    +    len=`expr $len - 2`                        # more verbose error message on OS/2
    +  fi
    +  if test $len -eq 29; then
    +    len=49                             # ??? Usually len=29???
     fi
     if test $len -eq 49  -a  -n "$pat"; then
     cat << EOT

)

Enjoy,
Ilya

 NOTE: the problem noted in 'program' is that install() does not work in your
 configuration$end, so you will not be able to use this feature. Otherwise you
 can safely ignore the above warning.
