Add dash as a valid characterl to UFS label name

[marck]

Summary

Most file systems and disk labeling schemes allow dashes as a valid character
in their names. Examples are MSDOS, GPT, and ext*

However, current implementation of UFS does not allow dashes.

style(9)? It should be indented with 4 spaces instead, right?

Shouldn't it be dash and underscore (singular, not plural) in this context? Also, missing Oxford comma (before and).

Here as well.

As noted, date at top of manual pages needs to be updated (which I will admit, I failed to do when I added underscores).

Plural is correct. `Legal characters are' describes all the legal things that can appear in a label of which there may be multiple alphanumerics, multiple dashes, and multiple underscores.
I agree that there should be a comma after dashes.

My same comment as above: leave plurals, add comma.

Agreed, should be four spaces.

Update language/style, as requested.

Sorry, unrelated changes chime in. Hope to eliminate them now.

Ahh, missed Oxford commas in manual pages.

Now all should be fixed.

[mckusick]

Looks good.

Dashes in labels won't cause problems for geom or the boot loader, so I think this is a good change. Thanks for driving it.

Note that update of manual page date fell out on corrective update.
