Keywords are:  'autounhide hide'

When hidden, by default your character will try to prevent you from using
commands that would reveal your hiding spot - for example, if you are hidden
and attempt to speak, you'll see a message like:

'Doing that would surely reveal your hiding place!'

This is to help newbie thieves from accidentally revealing their location
when trying to hide from something exceptionally dangerous.

With autounhide on, it is assumed that you know exactly what you are doing,
and you'll automatically unhide when using any commands.
