Is it really an intended behavior or just a typo that just hasn't been
noticed so far?

Wait... with the above choice, how do you distinguish the minus sign
from a space followed by an hyphen?

Yes, if the goal was really to distinguish them, then a space should
have also been added in UTF-8. Now, this isn't even specific to text
terminals: it is difficult to distinguish the minus sign from the en
or em dash in a graphical browser as well.
I think that there shouldn't be a need to distinguish them: the
context should be sufficient to make the difference (this is also
true for other characters that look the same). The space is even
worse, e.g. if one writes a sequence of expressions separated by
spaces: 0+1 2-1 3 4+5...
