Subject: [PATCH] Enable natural sorting on QCollator in
 KDirSortFilterProxyModel

KDirSortFilterProxyModel is advertised in the header as performing a
"natural sort", ie. "7 8 9 10 11", instead of a lexical "10 11 7 8 9".
However, as far as I can tell this was never true from the start, since
the collator responsible for the actual sorting did not have the
requisite numeric mode enabled, and this setting has always been off by
default as far back as I can find docs for it (Qt 5.2).

(Dolphin, which offers "natural sort", did not run into this issue
because it does not actually use
KDirSortFilterProxyModel.)
