fr: allow for b/foo/bar/ syntax as well

[eSoares]

@josemaia can you provide an example of how it should work?

[josemaia]

hello, friends b/friends/colleagues/ lopes: hello, colleagues

[eSoares]

Isn't that the same as "s/stuff/more stuff" ?

[josemaia]

yes, just nice to have an alternative syntax
