CVS commit: src/bin/sh

Modified Files:
        src/bin/sh: var.c

Log Message:
Fix a botch made in 1.70 (a bit over a week ago) where
        var=foo; readonly var=new
now fails.

If var was already set, an attempt to make it readonly, and assign it
a new value at the same time, failed - the readonly flag was set too soon.

Pointed out by Martijn Dekker (thanks).

Also, while here, add a couple of comments.
