demonstrated this issue.

since it is not MD and not related to the lowest level of profiling.
It will be moved, but getting it via <sys/gmon.h> already works.

is a bit off. In particular, Seventh Edition already used
the "linkflag" and "linkname" fields. Also, it appears that
there was no tar in Sixth Edition, contrary to what an earlier
tar.1 manpage claimed.
A few mdoc fixes also crept in here.

we do obey the size field for archives that we know are pax interchange

Also, clarify the comment explaining why this is necessary and explain
the (very unusual) conditions under which it might fail.

that's been called into question, so rather than argue about that (one
could make an excellent fair use argument), replace it with better
code since that's what FreeBSD is about.

[1] Bill called this a silly bikeshed. Maybe his is not incorrect.
shuffles the timing and sleep calls in bgfsck from:
sleep timer_on io timer_off io io io io io io io
to
sleep io io io io io io io timer_on io timer_off
The original method basically guaranteed that the timed I/O included a
disk seek every time, which made bgfsck sleep for much longer than
necessary.

a non-zero size but no body, some write a non-zero size and include
a body. To distinguish these cases, look for a valid tar header immediately
following a hardlink header with non-zero size.
Use em dashes instead of " - ".
Use .Em instead of *emphasis*.
