Ooops, sorry! My problem is that that output is too big, and many
parts are repeated... I was wondering that there could be functions
around that would split the original string into substrings with
constant properties, and also would rewrite that output in other
formats, putting one property-value pair in each line, sorting these
pairs by property name, and maybe doing something nice with the
keymaps... I am trying to write something like that myself, but I
thought that maybe I could be reinventing the wheel...
