largefiles: make cat on standins do something

cat of a standin would silently fail.

The use of standins is mostly an implementation detail, but it is already a bit
leaking. Being able to see the content of standins might be convenient for
debugging.

while lines:
    l = lines.pop(0)
    if l.startswith('SALT'):
        print l[:-1]

        snippet = l[4:]
        while lines and lines[0].startswith('... '):
            l = lines.pop(0)
            snippet += "\n" + l[4:]
        c = compile(snippet, '<heredoc>', 'single')

            exec c in globalvars, localvars
