Right, normally they do, but when singles are inside doubles,
their meaning is turned off by the double quotes, so that they're
treated as just normal characters.
For instance:
echo "'"
..is one way to echo a single quote.
If the single quote's normal operation were not disabled by the double
quotes, then that command would failing because there's no closing
single quote.

Yes, that's basically your V2 patch which seems to work.

It certainly was a common thread on comp.unix.shells, or whatever
the heck that usenet group for the shells was in the 90's.
Bourne quoting is certainly better thought out than csh's.
