* [PATCH] errno: add numbers to the errno-names

  To: linux-man-u79uwXL29TY76Z2rM5mHXA; +Cc: Wolfram Sang

Kernel logs often print errnos as '%d', so having the numbers next to the
defined names in the man-page is convenient to find out what went wrong.
Also move the indentation from 16 to 21 to make the numbers fit.

Signed-off-by: Wolfram Sang <w.sang-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>
---

The errorcodes were inserted by a little awk-script which parsed the numbers
directly out of the Kernel include-files.

The script also noted the following not mentioned error-codes:

ERFKILL (132) unused!
EOWNERDEAD (130) unused!
EHWPOISON (133) unused!
ENOTRECOVERABLE (131) unused!
