Sounds good, and I can work on the patch.  I think I like the first solution 
better, if we can come up with something elegant: the second case will force us 
to define priorities, and besides we already have kbd-help in addition to 

What about the following: before performing a conversion, 
substitute-command-keys could check a property of the string that it receives, 
say help-echo-conversion, and if that property is nil it would not perform the 

Alternatively, there's the option of performing conversion only on those
