A couple of comments on this commit:

- Can't we do this more simply using a decent regexp?
- Reading the code, e is not longer accessible to users at all.
- Could you document what the aim of this code? For example what
substitutions are you trying to make? That will make it a lot easier
to tell users what should work.

Cheers

Rich.
