Mark usage function as __dead2 in programs where it does not return2023-07-07T16:45:18ZAlfonso Gregorygfunni234@gmail.com2023-07-07T16:39:23Zurn:sha1:498a0a9c61c3048b492937ff76d58bbd0b78031a
In most cases, usage does not return, so mark them as __dead2. For the
cases where they do return, they have not been marked __dead2.

cmp: fix -s (silent) when used with skip offsets2021-01-11T00:02:56ZEd Masteemaste@FreeBSD.org2021-01-11T00:02:56Zurn:sha1:80445b7a3f738e0b0a33ee7a11905a275346a6de
-s causes cmp to print nothing for differing files, for use when only
the exit status is of interest.
-z compares the file size first, for regular files, and fails the
comparison early if they do not match.
Prior to this change -s implied -z as an optimization, but this is not
valid when file offsets are specified. Now, enable the -z optimization
for -s only if both skip arguments are not provided / 0.
Note that using -z with differing skip values will currently always
fail. We may want to compare size1 - skip1 with size2 - skip2 instaead,
and in any case the man page should be clarified.
