In case anyone experiences this bug and goes looking for help on it:  the
symptom is that tar will hang when parsing -T files with white space at
the front on a line.

  $ echo "bar" | tar -cvf t.tar -T -
  bar
  $ echo " bar" | tar -cvf t.tar -T -
  [...hangs...]^C


I believe this particular problem was introduced during development of
v1.27 (so it's not found in 1.26 and earlier).
