The 'msghdr' structure includes a field of type 'iovec',
so show the definition of that structure in this page.

No actual change to formatted output, but this makes the
page sources more consistent for the purpose of grepping, etc.

For a non-blocking socket, POSIX.1-2001/2008 allow either
EAGAIN or EWOULDBLOCK to be returned in cases where a call
would have blocked. Although these constants are defined
with the same value on most Linux architectures (PA-RISC
is the exception), POSIX.1 does not require them to have
the same value. Therefore, a portable application using
the sockets API should test for both errors when checking
this case.
(NB POSIX.1 only mentions EWOULDBLOCK in the context of
the sockets interfaces.)
Change made after a note cross-posted on linux-arch@vger,
http://thread.gmane.org/gmane.linux.debian.ports.hppa/5615
and a suggestion for write(2) from Carlos O'Donell

In the kernel, the error on encountering a mandatory lock is
EAGAIN. Although EAGAIN and EWOULDBLOCK are the same on
most Linux architectures, on some they are not, so don't
mention EWOULDBLOCK as it is misleading. (Mea culpa.)

Target file cannot be opened in append (O_APPEND) mode
In kernels prior to v2.6.27 splice() to a file in append mode is broken,
and since that version it is disallowed. It is possible this behaviour
may change in the future; see the kernel commit message
(efc968d450e013049a662d22727cf132618dcb2f) for more information.

In SEE ALSO, when a few man pages are referenced, those are divided by commas.
Every reference is on a separate line, and all lines but the last one should
end with comma. I spotted one place where there is no comma in between
references, and mocked up an awk script to find similar places:
for f in man*/*; do awk '/^.SH ["]SEE ALSO["]/ {sa=1; print "== " FILENAME " =="; print; next } /^\.(PP|SH)/ {sa=0; no=0; next} /^\.BR/ { if (sa==1) { print; if (no == 1) print "Missing comma in " FILENAME " +" FNR-1; no=0 } } /^\.BR .*)$/ { if (sa==1) no=1; next } /\.\\"/ {next} /.*/ { if (sa==1) { print; next }}' $f; done | fgrep 'Missing comma'
This patch fixes all the places found by the above script.
Also, there is an extra dot at the end of uri.7 "SEE ALSO" section.
Removed as per man-pages(7) recommendation.

The POSIX timers API is implemented (mostly) within the kernel,
so thse interfaces are system calls. Although there are as yet
no man pages, when they are added they should be in Section 2,
not 3. Therefore fix those pages that currently refer to these
interfaces as being in Section 3.

While writing a little program using capset
I found the capset manpage quite light on crucial
details and I had to resort to RTFS.
This patch improves the points I found unclear
and also moves one misplaced paragraph around.
