 Log Message:
 PR bin/57773
 
 Fix another bug reported by Jarle Fredrik Greipsland and added
 to PR bin/57773, which relates to calculating the length of a
 positional parameter which contains CTL chars -- yes, this one
 really is that specific, though it would also affect the special
 param $0 if it were to contain CTL chars, and its length was
 requested - that is fixed with the same change.  And note: $0
 is not affected because it looks like a positional param (it
 isn't, ${00} would be, but is always unset, ${0} isn't) all
 special parame would be affected the same way, but the only one
 that can ever contain a CTL char is $0 I believe.  ($@ and $*
 were affected, but just because they're expanding the positional
 params ... ${#@} and ${#*} are both technically unspecified
 expansions - and different shells produce different results.
 
 See the PR for the details of this one (and the previous).
 
 Thanks for the PR.
 
 XXX pullup to everything.
