Bad performance characteristics of `stripTrailing` etc...

[hderms]

using s.replaceFirst causes the regex to be compiled over and over again and this is called in a tight loop. I don't have any numbers to back this up but it's almost certainly making the library much slower than it needs to be.

You are right.
To be honest I was not concerned with performance when I have developed this lib.

If you would like to contribute, you are most welcome.
