[arm-allstar] WARNING: Exclamation Explanation - Don't use it

[Doug Crompton]

Don,

 The "!" in bash is used for history expansion. To use it you would have to
either enclose the password in single quotes 'this is my password!' or
escape the "!" as in -   this is my password\!

I am not absolutely sure this works in passwords but it does elsewhere. You
can give it a try and report back your findings.
