[issue27737] email.header.Header.encode() crashes with IndexError on spaces only value

[Tim Graham]

New submission from Tim Graham:

Python 2.7:
>>> from email.header import Header
>>> Header(' ').encode()
''

Python 3.2+ (I didn't check older versions of Python 3):
>>> Header(' ').encode()
Traceback (most recent call last):
  File "", line 1, in 
  File "/home/tim/code/cpython/Lib/email/header.py", line 391, in encode
value = formatter._str(linesep)
  File "/home/tim/code/cpython/Lib/email/header.py", line 427, in _str
self.newline()
  File "/home/tim/code/cpython/Lib/email/header.py", line 439, in newline
self._lines[-1] += str(self._current_line)
IndexError: list index out of range
