Why is that not desired?

Before my patch, the Compose.pre file contains many cases where
you can use for example the keysym slash in two orders but the
keysym KP_Divide only in one order, like  this:

$ grep Ø ./nls/en_US.UTF-8/Compose.pre
<dead_stroke> <O>                       : "Ø"   Oslash # LATIN CAPITAL LETTER O WITH STROKE
<Multi_key> <slash> <O>                 : "Ø"   Oslash # LATIN CAPITAL LETTER O WITH STROKE
<Multi_key> <O> <slash>                 : "Ø"   Oslash # LATIN CAPITAL LETTER O WITH STROKE
<Multi_key> <KP_Divide> <O>             : "Ø"   Oslash # LATIN CAPITAL LETTER O WITH STROKE

This is nonsense, why should the user care whether to use slash or
KP_Divide and why should there be such subtle differences?

If “<Multi_key> <slash> <O>” and “<Multi_key> <O> <slash>” both work and
produce the same result, then it makes no sense that when using
KP_Divide instead of slash, only one order works.
