MFC r220903: sh: Do not word split "${#parameter}".

This is only a problem if IFS contains digits, which is unusual but valid.

Because of an incorrect fix for PR bin/12137, "${#parameter}" was treated
as ${#parameter}. The underlying problem was that "${#parameter}"
erroneously added CTLESC bytes before determining the length. This
was properly fixed for PR bin/56147 but the incorrect fix was not backed
out.
