Thanks Andy!  I'll try this, but I have a concern:
In either case one of the signal names goes away, right?
Xhome or Xmaxlim gets deleted one way or another, so 2 signal names cannot be 
assigned to a single pin.

Just use the same signal name in both places, ie delete the "linksp
Xhome <= ppmc.0.din.02.in-not"  line and edit the
"linksp Xhome => axis.0.home-sw-in" line to say "linksp XMaxlimit =>
axis.0.home-sw-in"

You can freely edit the signal name to be more descriptive if you wish.

Alternatively you could do it all on one line with:

net anysignalnameyoulike  ppmc.0.din.02.in-not =>
axis.0.pos-lim-sw-in   axis.0.home-sw-in
