Transform some of them into copyright lines.
Also fix three header lines and snip some trailing whitespace.

The high-level libblkid API uses /run/blkid/blkid.tab cache to
store probing results. The cache format is
<device NAME="value" ...>devname</device>
and unfortunately the cache code does not escape quotation marks:
# mkfs.ext4 -L 'AAA"BBB'
# cat /run/blkid/blkid.tab
...
<device ... LABEL="AAA"BBB" ...>/dev/sdb1</device>
such string is later incorrectly parsed and blkid(8) returns
nonsenses. And for use-cases like
# eval $(blkid -o export /dev/sdb1)
it's also insecure.
Note that mount, udevd and blkid -p are based on low-level libblkid
API, it bypass the cache and directly read data from the devices.
The current udevd upstream does not depend on blkid(8) output at all,
it's directly linked with the library and all unsafe chars are encoded by
\x<hex> notation.
# mkfs.ext4 -L 'X"`/tmp/foo` "' /dev/sdb1
# udevadm info --export-db | grep LABEL
...
E: ID_FS_LABEL=X__/tmp/foo___
E: ID_FS_LABEL_ENC=X\x22\x60\x2ftmp\x2ffoo\x60\x20\x22

The standard format is to seperate each entry with a comma, and
for each one to be on a line by itself. Most util-linux pages
follow this, but a few do not.

Furthermore, explain the device argument right at the beginning,
since it is not an option, and alphabetize -k.

Now libblkid (the cache based part) tries to probe for the cached
filesystem firstly. This optimization is broken, because:
* new another superblock could be on the device and the original
is already obsolete
* we still need to probe for partitions and raids
* the code was too fragile
The patch also suggests lsblk --fs in blkid.8 for end users. lsblk
read information from used db.

The tool misspellings (https://github.com/lyda/misspell-check)
detected several typos. Command used:
$ git ls-files | grep -v ^po/ | misspellings -f -
* isosize: Fix typo in usage string.
* configure.ac: Fix typo in help string of --enable-most-builds option.
* fdisk: Fix typo in man page.
* libblkid, blkid, mount: Likewise.
* Fix various typos in docs and in source code comments.

Update the man pages of blkid, wipefs, fallocate, fstrim, losetup
and hexdump to clarify the suffixes for the numerical values of the
offset and size/length arguments regarding KiB=1024 vs KB=1000.
Also mention the ZiB/YiB and ZB/YB suffixes supported by strtosize().

Why?
* read-only root
* /etc is pretty bad place for caches
* all is usually cached by udev in /dev/disk/by-* and libblkid
is able to use these symlinks
* boot persistent cache is attractive for very small subset of
Linux machines (and they already need extra udev tunning otherwise
udev will probe all block devices during boot)
* the default is possible to override in /etc/blkid.conf
The systems without /run directory will not be affected by this
change.

The option does not have any effect, the original functionality was
removed from e2fsprogs in year 2003 by
commit 50b380b4d4ab668bad45033e3a8aaf93c7f42844
git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git
So.. don't propagate the option to users in year 2012 :-)

Use dates without the day, use the full month name, put "util-linux" in
the lower left corner, and "User Commands" or "System Administration"
at the top center.
Also improve here and there the one-line program description.

This output format is similar to 'udev' but without udev specific
prefixed (e.g. ID_FS_*). The 'export' format is automatically enabled
for I/O Limits (-i).

This option allows to restrict low-level probing to the defined list
of superbocks (filesystems or RAIDs). For example:
blkid -p -n ext3,ext4,vfat /dev/sda1
or
blkid -p -n novfat /dev/sda1

... sad story, I have temporary disabled pretty-output code
in very early version of blkid.c in u-l-ng. (It was also in
time when pretty-output was very new feature in e2fsprogs.)
Unfortunately, the -L option (shortcut to "-o list") in u-l-ng version
was reused for for any other functionality few months later.... this
stupid thing was released in u-l-ng 2.15 and 2.16 without any negative
feedback from users.
It means the blkid from u-l-ng is not backwardly compatible with
the original version from e2fsprogs. The -L option has a different
meaning there.
I'm sorry about this bug...
This patch:
* enable pretty-output (-o line)
* add a note about incompatibility between u-l-ng and e2fsprogs
to blkid.8 man page

The others utilities are in one of the top-level directories. That's
confusing to have blkid(8) and findfs(8) in shlibs/ tree.
