I discovered this behaviour, in not quite so dramatic form, when I was 
developing pdfmark.tmac; in my case, I didn't introduce unintentional 
recursion, but I did find that redefining either of a pair of mutual 
aliases affected both.  That seemed natural to me, at the time.

It is good to clarify this, in the documentation; just one very minor 
nit...

"With other words" is a direct translation of the German idiom.  It 
seems stilted in English, where the idiomatically correct expression 
is "In other words".
