Testing for regkey (not value) existence

[banaman8d]

Did you test that macro?

With the 2 beta 4 NSIS, I get a compilation error on line 5 of the macro when I give it the following:

!insertmacro "HKLM" "Software\Microsoft\Updates\Windows Server 2003\SP1" "KB823980"

The error is:
Invalid command: LoopReg_Software\Microsoft\Updates\Windows

The spaces create an invalid label, but it is a perfectly legal key.

I have attached a fix for the script...
but in order to workaround I needed to make the jumps relative to avoid naming problems.
