Workaround

Running gdb with latest pretty printers causes:

Traceback (most recent call last):
  File "<string>", line 3, in <module>
  File "/data/utils/prettyprinters/libstdcxx/v6/printers.py", line 1056
    """
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in
position 194-195: malformed \N character escape
/home/marjobe/.gdbinit:6: Error in sourced command file:
Error while executing Python code.

The problem is that a comment contains an escape sequence. See workaround in
the attached patch.
