When /proc/pid/fdinfo was part of proc.5 man page the indentation made
sense. As a standalone man page the indentation doesn't need to be so
far over to the right. Remove the initial tagged pragraph, move the
"since Linux 2.6.22" to a new history subsection.

Thanks!  I've applied it, and amended with some minor tweaks.
