I didn't really tried to understand the way your style works, I only
tested it :) But if I have some more time, I'll have to learn TeX, it
seems unavoidable :)

Ok, I see. But my example did as well not escape the backslash in


which results in

	(indexentry :tkey ( ( "Euler" "\textsc {Euler}" ) )
		    :attr "definition" :open-range :locref "1")

This was my original question and it is in contrast to the examples you
gave and I'm not sure if I did something wrong.

I just had another close look and it seems that your version does
*only* work in conjunction with \usepackage{german}.

I tested it once more and *without* german.sty the quotes aren't
doubled. This is maybe the reason for my problems.

without german.sty:
	(indexentry :tkey ( ( "Euler" "\textsc {Euler}" ) )
		    :attr "definition" :open-range :locref "1")
with german.sty:
	(indexentry :tkey ( ( "Euler" "\\textsc{Euler}" ) )
		    :attr "definition" :open-range :locref "1")

[5 min later.]

I just saw that you have already fixed this bug :) Ok. then forget
about it.

Aargh! It seems that this is a very confusing week. I have have
overlooked so many things, this week. Stupid stuff this... :)
