#!/bin/sh doesn't show

[cortman]

Hi,

Why is it that when you write out a script in moin moin and put it
between code tags-

{{{
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
}}}

the #!/bin/sh disappears in the finished wiki? It's still in the
syntax but doesn't show up when viewed.
We're trying to transfer information from the Ubuntu forums to the
wiki, so it is more widely available, but when it randomly removes
important parts of code, that's a problem.
Thanks for your attention.

Regards,
Cortman
