moby--moby/docker/flags.go
Doug Davis ae9bd580af Make --tlsverify enable tls regardless of value specified
I also needed to add a mflag.IsSet() function that allows you to check
to see if a certain flag was actually specified on the cmd line.

Per #9221 - also tweaked the docs to fix a typo.

Closes #9221
