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.
