Feature request: IndentWiseNextUpwardIndent

[jrochel]

I wish there were a function IndentWiseNextUpwardIndent which behaves like IndentWiseNextGreaterIndent never allowing to jump beyond any line with a smaller indent level.

An example:

A
	B
C
	D
		E

Starting from A effectuating a IndentWiseNextUpwardIndent/IndentWiseNextGreaterIndent gets me to B.
On B a IndentWiseNextGreaterIndent gets me to E which I never need to do. (There is no semantic link betwen B and E).
Instead I wish to stay "stuck" on B. Would it be possible to add IndentWiseNextUpwardIndent which has me go form A to B but not beyond B?
