Yup. Notice that it complained about a failing expansion of "${if" (i.e.
a truncated expression).
For pipe commands, each argument is separately expanded. This is so that
the results of the expansion cannot affect the division of the command
into arguments. This is particularly relevant when you are sticking data
from outside sources (e.g. $local_part) into commands.
