removing double blank lines using regex

[partof]

I don't understand why this code isn't working since the regex works fine (I need to change the double/tripple/... blank line, into a single).

Code: Select all

[code=autohotkey file=Untitled.ahk]^!Space::
	clipboard =
	Send, ^a
	Send, ^c
	ClipWait
	clipboard := RegExReplace(clipboard, "^[\r\n]{2,}","\n")
	sleep 100
	Send, ^v
	return

[/code]

Any idea what could be wrong?

It's getting closer: this one removes the multiple blank lines *when the text contains line breaks*, but... it adds an extra line when the text doesn't contain line break... Crazy...

Code: Select all

^!Space::
	clipboard =
	Send, ^a
	Send, ^c
	ClipWait
	clipboard := RegExReplace(clipboard,"\v\v+","`n`n") ; v find vertical tab char
	sleep 100
	Send, ^v
	return

Code: Select all

ClipBoard := RegExReplace(ClipBoard, "\R(?=\R{2,})")
; or
ClipBoard  := RegExReplace(ClipBoard , "\R\R\K\R+")
