cf4dc4a09d mount: "mount -o rw ...." should not fall back to RO mount
The reported case was an attempt to remount,rw a CD-ROM:

  mount -o remount,rw /mnt/sr0

which "succeeded" by falling back to RO:

  mount("/dev/sr0", "/mnt/sr0", 0x412862, MS_REMOUNT|MS_SILENT|MS_RELATIME, "nojoliet,check=s,map=n,blocksize"...) = -1 EROFS (Read-only file system)
  ...
  mount("/dev/sr0", "/mnt/sr0", 0x412862, MS_RDONLY|MS_REMOUNT|MS_SILENT|MS_RELATIME, "nojoliet,check=s,map=n,blocksize"...) = 0

Clearly, not what was intended!

eb048a450c ps: fix -o pid=PID,args interpreting entire "PID,args" as header
procps-ng 3.3.15 does not do this.
(It could, allowing commas in headers and requiring
"ps -opid=PID -oargs" form for this case, but it does not).

421c8767ba find: Unify time comparisons
Split the common part into a function, to be reused.

The tail call is optimized, meaning now mmin/mtime just prepare arguments
and jump into the common code, thus near zero overhead.

This reduces code size slightly, e.g. on x86_64:
   text    data     bss     dec     hex filename
   4806       0       0    4806    12c6 findutils/find.o.orig
   4782       0       0    4782    12ae findutils/find.o

Of course, the savings are even greater when implementing atime/ctime
variants.

ed9aa89269 wget: implement --post-file
Add the --post-file option to send form data from a file.  As with
--post-data it's up to the user to ensure that the data is encoded
as appropriate:  all wget does is stuff the provided data into
the request.

The --post-data and --post-file options are mutually exclusive and
only one instance of either may be given.

Additionally:

- update the usage message to include missing details of the --post-data
  and --header options;

- free POST data if FEATURE_CLEAN_UP is enabled.
