Great.

Why?  Given the definition above, I can insert an en-dash with spaces
around |--| like this |--| and I can insert an en-dash without
spaces-|--|-by surrounding it with hyphens (which is sometimes needed,
too).  This is very handy, so in fact I'd rather want the "trim"
attribute *not* to have to match the context of the substitution
reference.

Supporting multiple substitution definitions only differing in their
trim-attributes would add a lot of unnecessary complexity, and I'm not
convinced at all that we are ever going to need it.

So I think we rather shouldn't make substitutions context-sensitive.
