Bug#776492: wiki.debian.org: wiki system swallows shebang when rendering to HTML

[john <none@example.org>]

Package: wiki.debian.org
Severity: important

Dear Maintainer,
posting a (shell) script inside "{{{" / "}}}" tags onto a wiki page makes the
wiki system omit a shebang from the beginning of the script when rendering
to HTML.
This can lead to people not being able to follow instructions from the wiki.

Example:
Trying to use the instructions from wiki.debian.org/ZRam fails, because the 
posted script doesn't have a shebang (anymore). Hitting the "edit" button shows
that the shebang is actually there in the wiki markup source code, though.
