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
