A ChangeLog entry should generally describe what a patch changes, not
what it does.  So this should mention a new variable canonical_order,
a new function arch_canonicalize, and the call to pass alts through
it.

Unexpect -> Unexpected

prefixs -> prefixes

rest multi-char -> rest of the multi-char

This looks good to me with the minor English improvements Andreas and
I suggested.
