Well, but are you sure that awk didn't misbehave?
An extended regular expression can be used to separate fields by using
the -F ERE option or by assigning a string containing the expression to
the built-in variable FS. The default value of the FS variable shall be
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
a single <space> character. The following describes FS behavior:
^^^^^^^^^^^^^^^^^^^^^^^^^^^
(1) If FS is a single character:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(a) If FS is <space>, skip leading and trailing <blank>s;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
fields shall be delimited by sets of one or more <blank>s.
So it should skip the trailing blank.
