uri(7) documents that "Older documents suggested inserting the
prefix 'URL:' just before the URI, but this form has never
caught on." and advise to "enclosed in angle brackets" (and a
few other alternatives).
This patch removes an instance of 'URL:' from the page.

I didn't like ithe "SIGKILL operates similarly, with exceptions"
phrase (if it's different, then it's not "similar", right?),
and now I got around to changing it. Now it says simply:
"SIGKILL does not generate signal-delivery-stop and therefore
the tracer can't suppress it."
Replaced "why WNOHANG is not reliable" example with a more
realistic one (the one which actually inspired to add this
information to man page in the first place): we got
ESRCH - process is gone! - but waitpid(WNOHANG) can still
confusingly return 0 "no processes to wait for".
Replaced "This means that unneeded trailing arguments may
be omitted" part with a much better recommendation
to never do that and to supply zero arguments instead.
(The part about "undocumentedness" of gcc behavior was bogus,
btw - deleted).
Expanded BUGS section with the explanation and an example
of visible strace behavior on the buggy syscalls which
exit with EINTR on ptrace attach. I hope this will lead
to people submitting better bug reports to lkml about
such syscalls.

For IOPRIO_WHO_PGRP, who==0 means operate on the caller's
process group.

Mainly rewording things like "is delivered" to "becomes pending",
which is more accurate terminology.

This system call was never visible to user space, so it makes
sense to move it out of the main table of system calls into
the notes below the table.

Reduce the chance that the reader may be misled into thinking
that there is a wrapper function for this system call by noting
explicitly in the SYNOPSIS that there is no glibc wrapper and
pointing the reader to NOTES for further details.

Improve the example demonstrating allocation of a buffer
for readdir_r() to handle -1 error return from pathconf().
Otherwise, naive readers may think that pathconf() return
value can be used without checking.
