Well, in the print shops with their proportional fonts it becomes often
VERY difficult to tell where a space should go and where not.
This statement deals with redirection of input, so there MUST NOT BE A
SPACE in  "<t:qwe"   !!!

BTW, in my version this whole part of the script looks a bit different:
type env:loop
eval <env:loop >NIL: to=t:qwe{$$} value2=1 op=- ?
copy t:qwe{$$} env:loop  ; don't abuse type where copy is meant
