Document wildcards and ampersands.

[trasz]

Summary

Document use of wildcards (*) and ampersands (&) in autofs map files.

[wblock]

usr.sbin/autofs/auto_master.5

129

Some concerns on wording, passive voice, the semicolon, and a contraction. Maybe:

A wildcard
.Pq Ql *
can be used for the key.
It matches every directory that does not match other keys.

164–174

s/pass/pass a/

168

Can be more declarative with rearrangement:

Ampersands
.Pq .Ql &
in the
.Ar location
field are replaced with key.

("the key"? I'm not sure.)

169

Repetitive on "this", but the second one can be removed.

176

s/with/with a/

Fixes from wblock@.

One more comment (sorry), but that's all.

usr.sbin/autofs/auto_master.5

168

This still bothers me. An unsophisticated reader might think "key" is a literal value. Maybe

are replaced with the value of
.Ar key .

[trasz]

Quote the key, and fix syntax used with ampersand, so it renders properly.

Thanks!
