OK, that's almost the same, but seems cleaner. And since I'm keeping
the ewoc in a global variable (there is no point in having more than one
instance in my use-case), it is also trivial.

Thanks. I ended up with squeezing a `propertize' between `insert' and
`format'. This has a disadvantage (AFAIU) of creating a copy of the
string, but since my ewoc won't have more than, say, 100 elements,
I don't think it will slow things down a lot.
