solaris /usr/ucb/tr fixes edit-pr tr: Bad string.

[doug . mildram]

Surprised that I havent seen this bug reported on this list.
(maybe linux is overwhelmingly more active than Solaris here!)

I've finally debugged "edit-pr" under Solaris (2.6, 2.7, ...)
In truth, there are other (smaller?) bugs, but I'll report them today
          and keep them out of THIS email.

Symptom:   edit-pr NNNN   under solaris may echo a handful of errors :
tr: Bad string
tr: Bad string
tr: Bad string
                        before bringing up EDITOR.

FIX:    in  edit-pr, there are (3) instances of  something | tr  .....
                      around lines 180-190.  I changed all (3) "tr"
                       to $TR_CMD, and set   TR_CMD="/usr/ucb/tr"

MORE ANALYSIS:  Solaris has some commands in BOTH /bin 
                                    (maybe older or sysVish)
                             and possibly ALSO in /usr/ucb
   while your $path MIGHT have /usr/ucb first, /bin is often before.

Solaris /usr/ucb/tr  can handle what edit-pr feeds it, e.g.:

solaris%  cat /tmp/trtest
>Audit-Trail: 
<Log of specific changes to the PR (multiple lines)> 

solaris%   cat /tmp/trtest  | /usr/ucb/tr '][*+^$|\()&/' '............'
>Audit-Trail: 
<Log of specific changes to the PR .multiple lines.> 

solaris%  cat /tmp/trtest | /bin/tr | tr '][*+^$|\()&/' '............'
tr: Bad string.
