Close enough:
:setl foldenable foldmethod=expr foldminlines=0
foldexpr=getline(v:lnum)=~'^#'?1:0 foldtext=v:folddashes foldlevel=0
fillchars-=fold:-

which makes it:
-
code
-
code
-
code

I was just going to suggest trying the NrrwRgn Plugin, which allows to
Narrow several non-continous regions like that. But the result of
:v/^#/NRP
:NRMulti
looks like this:
# Start NrrwRgn1
code1
# End NrrwRgn1

# Start NrrwRgn2
code2
# End NrrwRgn2

# Start NrrwRgn3
code3
# End NrrwRgn3

Which doesn't really help you either. (Those start and stop markers are
needed by NrrwRgn to let the plugin later associate each part to where
it belongs in the original buffer.

Christian
