Is it possible to use a reverse direction for offset

[François]

The text source is not very big.

However I implement transcoding from one language to another and I do an VERY large amount of search and replace.

I think I have quite optimized my LC code but transcoding can take 5 minutes to do, and I need the whole process to chase unexpected bugs. This is using the forward search (offset) most of the time.

Using a standalone app takes the time down to 4 minutes, which is not a sufficient gain for my usage.
