  but the question remains, are people using that weird combination
*deliberately*, if it in fact gives you the combination of the two
effects? as in, are people writing:

  VAR_append += "string"

when it would be equivalent to write

  VAR_append = " string"

simply because they're too lazy to add the leading space?
