While I don't mind the change as is, "sort" is ambiguous here in one regard.
Personally I'd prefer if those parts of the change were dropped, but I can
live with the sorting criteria being spelled out in the description:

Imo this sorting was fine (at least one further instance below): Whether
underscore sorts ahead of lower case letters depends on how sorting is done.
I take you assume sorting as per the C locale, when the original sorting was
considering undercores to be separators, i.e. in a different character class
(together with e.g. dash or tilde).

When using C local sorting, I think arch-x86/xen-@arch@.h also would need
moving past arch-x86/xen.h (whereas right now all separators are deemed
equal and hence @ comes ahead of h which in turn is ahead of m).
