Is there any chance we can take this opportunity to make "h"/"H" the
preferred aliases?  Using "'" in bourne-style shells is very
annoying[1], and I suspect it's also creating unnecessary complications
elsewhere.

Alternatives:

- Completely kill "'" (I'd prefer this, but I realize it's complicated
  with descriptors already being used widely).  If "h"/"H" are made the
  preferred aliases, maybe it'd be enough to make implementing "'" a
  SHOULD rather than a MUST; this would push implementations towards
  displaying descriptors using the h versions for maximum compatibility.

- Calculate the checksum over s/(h|H)/'/ (again, I know that's
  complicated with descriptors already widely used)

Thanks,

-Dave
