Thanks, Peter :)

If it's any consolation, only files which are opened only as O_RDONLY are
massaged to be opened with the special O_TEXT attribute.  All O_WRONLY
and O_RDWR are left alone, which I hope, will produce the correct
semantic.  Since shells are primarily dealing with textual data I feel
this is a sufficient trade-off.  I will, of course, be following this
issue and report if there are any problems (which I'll probably have to
fix, since I opened this can'o'worms myself :)  But, as you say, time
will tell.
