I was able to do this using bash and Busybox echo with no problems.

----------------

$ H="$HOSTNAME:" && ./busybox echo $H
shiva:
$ H="$HOSTNAME/" && ./busybox echo $H
shiva/
$ H="$HOSTNAME+" && ./busybox echo $H
shiva+
$ H="$HOSTNAME/" && ./busybox echo $H
shiva/

----------------

I was not able to run the test in Busybox shell because I found another bug.

I ran your test script on my own box and it ran just fine under both bash and
Busybox shell.

----------------

$ cat u-bug.sh 
#!/bin/sh
 
./busybox cat - <<!*
alfa~
bravo/
charlie;
delta+
!*
 
$ ./u-bug.sh 
alfa~
bravo/
charlie;
delta+
$ ./busybox sh


BusyBox v0.50pre (2001.03.02-16:46+0000) Built-in shell (lash)
Enter 'help' for a list of built-in commands.

$ ./u-bug.sh
alfa~
bravo/
charlie;
delta+

----------------

Looks like an ash bug to me.
