Increasing indent factor in script windows

[Mark Powell]

Is there any way to increase the indent factor in script windows?  (i.e. instead of having the engine indent by two spaces per tier, have it indent by four, for example).  I would like to have a more pronounced nesting.

Alternately, I extract scripts for purposes of documentation and can write a handler to increase it.  But I am a bit stumped by the most basic thing.  How do I say in a script the equivalent of

"if line x of script has leading spaces then double the number of leading spaces"

without resorting to heavy handed repeat loops?

Appreciate your help.
