It works, if you try this
test.rb  # put it on a file and run by ruby not irb
 
str = <<'EOF'
"an escaped\" quote"
"an escaped\\\" quote"
EOF
str.each_line{ |line|
  p line
  p line.scan(/"(?:[^\\"]+|\\.)+"/).collect! {|e| e.sub!(/^"(.*)"$/, '\1')}
}
 
For your example, I think the problem is on irb:
try this on irb and you know what I mean.
irb(main):001:0> '\\'.length
1  # see, it is 1 not 2, kind of in irb simple quote string still substitute \\
irb(main):002:0>

/usr/home/howardat > irb

irb(main):001:0> '"an escaped\" quote"' =~ /"((?:[^\\"]+|\\.)+)"/ && puts("(#{$1})")
(an escaped\" quote)
=> nil

irb(main):002:0> '"an escaped\\\" quote"' =~ /"((?:[^\\"]+|\\.)+)"/ && puts("(#{$1})")
(an escaped\\)
=> nil

this doesn't seem to work?
