Please describe the problem:
Python code following a multiline double quoted string is highlighted correctly. But code following a multiline single quoted string is not if the string contains a newline.

Steps to reproduce:
Paste the following into gedit:

# Test case A
"""%s""" % ('blah')

# Test case B
"""%s""" \
% ('blah')

# Test case C
"""%s
""" % ('blah')

# Test case D
'''%s''' \
% ('blah')

# Test case E
'''%s''' % ('blah')

# Test case F
'''%s
''' % ('blah')

Actual results:
Test cases A through E are highlighted correctly. In test case F <<' % ('>> and <<')>>  get highlighted as strings.

Expected results:
In case F <<'blah'>> should be highlighted as a string.

Does this happen every time?
Yes
