Perhaps I'm missing the point, but what semantic have consecutive
backslashes substituting a string ? 
I feels like a bug, but probably isn't:
irb(main):008:0> puts "abcd".sub('abcd',"\\").length
1
irb(main):014:0> puts "abcd".sub('abcd',"\\"*2).length
1
irb(main):009:0> puts "abcd".sub('abcd',"\\"*10).length
5 

Thx a lot,
