This reverts most of commit 3d1237fb2ab4edb926c717767bb5e31d6053a7c5.
218e99
218e99
The commit claims to sort the output of "-device help" "by
218e99
functionality rather than alphabetical".  Issues:
218e99
218e99
* The output was unsorted before, not alphabetically sorted.
218e99
  Misleading, but harmless enough.
218e99
218e99
* The commit doesn't just sort the output of "-device help" as it
218e99
  claims, it adds categories to each line of "-device help", and it
218e99
  prints devices once per category.  In particular, devices without a
218e99
  category aren't shown anymore.  Maybe such devices should not exist,
218e99
  but they do.  Regression.
218e99
218e99
* Categories are also added to the output of "info qdm".  Silent
218e99
  change, not nice.  Output remains unsorted, unlike "-device help".
218e99
218e99
I'm going to reimplement the feature we actually want, without the
218e99
warts.  Reverting the flawed commit first should make it easier to
218e99
review.  However, I can't revert it completely, since DeviceClass
218e99
member categories has been put to use.  So leave that part in.
