Does this accommodate languages for which line breaks are mandatory? If
so, I guess some encoding scheme would be necessary to convey line
endings (basically the inverse of what flow-fill.el provides) so that
<pre>-flowed formatting can be reconstituted on the recipient's end.
Perhaps some un-spoken-for control char in the lower ASCII range could
be borrowed for this purpose in a tr(1) style 1:1 swap.

Also, what about snippets spanning multiple messages?

I've heard folks in the know speak of folding (in the outline/hs sense)
with regard to multi-line messages:


In fact, I think this extension may be worth checking out and even
shooting for as a reference implementation for showing off whatever v3
lib we end up settling on.
