New Revision: 221522
URL: http://svn.freebsd.org/changeset/base/221522
Log:
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.
