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!

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).

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.

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.

Commit 9fe1548bb (date,touch: allow timezone offsets in dates)
mentioned the similarity between '@' format dates and those with
timezone offsets. It didn't notice that as a result there's
common code which can be shared.

Chmod used to incorrectly report as changed even files for which the
mode did not change. This was caused by extra bits in the st_mode, that
were not present when parsed from passed argument in the form of octal
number.

Allow ISO 8601 style dates to include a timezone offset. Like
the '@' format these dates aren't relative to the user's current
timezone and shouldn't be subject to DST adjustment.
- The implementation uses the strptime() '%z' format specifier.
This an extension which may not be available so the use of
timezones is a configuration option.
- The 'touch' applet has been updated to respect whether DST
adjustment is required, matching 'date'.

The default build uses strptime() in parse_datestr() to support the
'month_name d HH:MM:SS YYYY' format of GNU date. If we've linked
with strptime() there's an advantage is using it for other formats
too.
There's no change to the non-default, non-DESKTOP build.
