Antw: Re: `${PARAMETER:OFFSET}' does not work for negative offset

[Ulrich Windl]

I realized that ":-2" is ambiguous: Default value or substring? A SPC does 
disambiguate (now I know). I still wonder why the manual page does not change 
"${parameter:offset}" and "${parameter:offset:length}" to "${parameter: 
offset}" and "${parameter: offset:length}", respectively. Or change the wording 
of "If offset evaluates to a number less than  zero" to "If offset evaluates to 
a number less than  zero AND begins with a space"

You get the idea...

Yes, it was all my fault.
