Not true for me. (version 1.0.2)

The regular minus (display in leftmost corner of the window: "math -") looks 
identical to the negation (display in leftmost corner of the window: "math 
<um>") but the space afterwards is smaller (for minus infty just the same as 
for minus 1 or anything else)

If you don't see the difference: is it because you can't insert <um>, or 
because the <um> is not displayed any different from minus?

Furthermore: What do you mean by "much more" and "excessive"? Here it is just 
a tiny difference that only an expert would notice. (comparable to one vs. 
two spaces in math mode)

Furthermore: Is it only for /infty? I have the same behaviour for any 
following symbol.
