yet it will.  you (and you're by far not the first) misunderstood my
suggestion.  that would be exported as the string

	ascii=^b^a^a^b^b^a^c^a^d^a...

which could be easily re-imported.

let me sum up what i'm proposing:  es strings could legally include anything
other than the nul character (\0).  strings containing ^a and ^b would have
some filtering done on them for export and be unfiltered on import.  the
external representations would be slightly different than they are right now,
but if you never use control-a or control-b in strings, you wouldn't notice
the difference.
