The size unit format is a longstanding annoyance. This patch is based on
the work of Nils and Alexandre and enhances the options. It's possible
to select raw bytes, SI-based or IEC-based compact units (human
frientdly) or a fixed base from kilobytes to terabytes. The default is
compact human readable IEC-based, no change to current version.

There are many trivial typos in Documentation/*.txt.
All of these use "exist status" to mean "exit status"
by mistake. I guess someone first made this mistake
and it has spread by copy-and-paste :-D

'btrfs filesystem defrag' has an option '-t', whose manpage says
"Any extent bigger than threshold given by -t option, will be
considered already defragged. Use 0 to take the kernel default, and
use 1 to say every single extent must be rewritten."
Here 'use 0' still works, it refers to the default value(256K), however,
'use 1' is an obvious typo, it should be -1, which means the largest value
it can be.
Right now, we use parse_size() which no more allow value '-1', so in
order to keep the manpage correct, this updates it to only keep value '0'.
If you want to make sure every single extent is rewritten, please use a fairly
large size, say 1G.

The asciidoc conversion was done on a development branch and there are
portions of text that do not reflect the code.
