 there are some provisions for spaces in text but for verbatim it is a
bit more tricky


you now see visual spaces show up that can be copied

now, say that we add real spaces, which you can do after and this (in

\setvalue{\??typingspace\v!character}{\chardef\obeyedspace32 }

and then:


in sumatra pdf:

default   : spaces are copied as spaces (so three become three
on        : visual spaces for every one
character : funny newlines when more than two spaces 

OK, I see, thanks for the explanation! Indeed, when I look at the
makeup, there is no glue there to offset the line. But in Okular it just
ignores those spaces.

Unfortunately as I just found out, comments are also viewer dependent...
For instance in Firefox, indentations are lost. 

So for now, attached files for longer snippets and visual spaces with a
string replacement operation afterwards are the way to go it seems.
