Here documents in ash shell scripts mess up stdin on 9x

I always wondered why configure screwed up bash
on win95, and I finally figured it out.

Here documents in ash shell scripts

This bug doesn't appear under NT4 SP3.

--------------------  output starts here
Mikey:/usr/bin$ ./here2
testing
Mikey:/usr/bin$ cat here2
#!/bin/bash
cat <<!
testing
!
Mikey:/usr/bin$ ./here1
testing
Mikey:/usr/bin$ ccat here1
cat here1
"D:/usr/H-i586-cygwin32/bin/bash.exe": ccat: command not found
Mikey:/usr/bin$ cat here1
cat here1
#!/bin/sh
cat <<!
testing
!
Mikey:/usr/bin$               <--------- just pressed <ENTER>

Mikey:/usr/bin$ echo this
echo this
this
Mikey:/usr/bin$
------------------------- output ends here

arrow keys stop working for history,
and command line editing,
and any command entered from the command
line is echoed on the next line.
including just <ENTER> as you can see above.

BTW the ccat is not a typo the first character
pressed is repeated, and the cat here1
on the next line is exactly as it was typed.

Symptoms are the same if ash is the login shell. 
( except there is no history :)

Maybe time for a little cut/paste action bash->ash?
