mcstas-2.5 and master branch: issue with position of input parameters to mcdisplay

[willend]

With the attached instrument file, input parameters placed before ncount on the commandline are ignored, i.e.

mcdisplay pencilbeam.instr -n1e7 nslit=500 radius=0.0001 ROT=0

behaves correctly, showing

whereas

mcrun pencilbeam.instr ROT=0 -n1e7 nslit=500 radius=0.0001 

does not, instead showing a rotated guide element:

pencilbeam.instr.txt

[willend]

As a side note, mcrun works OK in this respect, so a solution for better handling of these instrument par=value pairs may be found there

I confirm this bug is still there in mccode-3
