Exactly how is a backticked command double-quoted? It just has `...`. Or
do you mean that its interpolation rules are the same as double quotes?

Unnecessary. This shows the double quote working unescaped:
$ perl -le 'print `ls "foo bar"`'
ls: foo bar: No such file or directory
$ touch foo\ bar
$ perl -le 'print `ls "foo bar"`'
foo bar

Your problem is not with perl, but with the bourne shell. People like me
welcomed Perl because it didn't have the frustrating quoting rules of
shells. Whatever works on the bourne shell command line, that's what you
use in backticks in Perl. Try comp.unix.shell.
