It might be handy to have some of the escapes that work in $'string'
quoting to also work in prompts especially now with the ${parameter@P}
transformation.Specifically the hex, unicode and control ones: \xHH, \uHHHH, \UHHHHHHHH and \cx. I presume that the dollar-single-quote escapes should not be touched since they are "specified by the ANSI C standard". Also, they needn't be since we have the @P transformation. -- Visit serverfault.com to get your system administration questions answered.
