What exactly do you want?
I tried:
IDL> plot,findgen(50)/50.*4.,findgen(50)^2,xrange=,$
IDL>
xtickv=,xticks=8,xstyle=1,xminor=8
and it produces minor tick marks until the very end. If you want to
omit the *label* at 4.5, you could do
IDL> plot,findgen(50)/50.*4.,findgen(50)^2,xrange=,$
IDL>
xtickv=[.5,1.,1.5,2,2.5,3,3.5,4.,4.5,5.],xticks=8,xstyle=1,x minor=8,$
IDL> xtickname=['.5','1','1.5','2','2.5','3','3.5','4',' ','5']
If you don't want a tick mark at 4.5 it becomes a little more
complicated. You would then have to use the axis command to create a
second axis with a ticklen paramater that is smaller.
