With the 'devnm' infrastructure fixed, it is quite easy to support
names like "md_home" for md arrays.
The currently defaults to "off" and can be enabled in mdadm.conf with
CREATE names=yes
This is incase other tools get confused by the new names.

action=re-add will only re-add a recently removed device if a
bitmap is present.
Otherwise a force-space is needed.

And here's another trivial bugfix, now for spelling mistakes in various
places, authred by Sergey Kirpichev (Cc'ed) and carried in debian mdadm
package.

As homehost defaults to the system name it is not possible to specify
a NULL homehost.
This patch restored this ability with either --homehost="" or
--homehost="<none>".
This allows the creation of v1.x arrays without a "hostname:"
prefix in the name.

If mdadm.conf contains
HOMEHOST <ignore>
or commandline contains
--homehost=<ignore>
then the check that array metadata mentions the given homehost is
replace by a check that the name recorded in the metadata is not
already used by some other array mentioned in mdadm.conf.
This allows more arrays to use their native name rather than having
an _NN suffix added.
This should only be used during boot time if all arrays required for
normal boot are listed in mdadm.conf.
If auto-assembly is used to find all array during boot, then the
HOMEHOST feature should be used to ensure there is no room for
confusion in choosing array names, and so it should not be set
to <ignore>.

For consistency with --create and --assemble, allow the array name
given in mdadm.conf to exclude the "/dev/md/" prefix. So e.g.
ARRAY home uuid=whatever
is treated like
ARRAY /dev/md/home uuid=whatever
Also exclude names which create_mddev will reject.

The line 'auto' in mdadm.conf can be used to disable assembly
of specific metadata types, or of all arrays.
This does not affect assembly of arrays listed in mdadm.conf
or on command line.
auto -all
will disable all auto-assembly.
auto -ddf
will cause mdadm to ignore ddf arrays that are not explicitly
mentioned, and auto assemble anything else it finds.

Sometimes we want to ensure particular arrays are never
assembled automatically. This might include an array made of
devices that are shared between hosts.
To support this, allow ARRAY lines in mdadm.conf to use the word
"ignore" rather than a device name. Arrays which match such lines
are never automatically assembled (though they can still be assembled
by explicitly giving identification information on the mdadm command
line.

Two places that should have been .B or .I were .M, which of
course is an error.
So fix these and that the opportunity to be more consistent
with highlighting of "mdadm". Make it always italic except when
used as a literal example, then bold.

nroff formats "-" as the very short hyphen used for hyphenated terms
and for splitting a word across two lines. When you want a literal
ASCII "-", like for typing on a command line, you're supposed to use
"\-" instead.
Yeah, it sounds pedantic, but it actually makes a difference. With
modern Unicode-capable terminals, "man" actually renders these with
different characters, so if you try to search for "--create" in your
favorite pager, you won't find it unless the nroff source says
"\-\-create". This discrepancy doesn't generally show up with
non-Unicode terminals.

This means the output of "mdadm -Es" can be used as a complete
