Provide option to avoid quoting values while dumping data

[deeparora29]

Is there a way we can provide option to avoid this quoting string values while dumping strings when they have special characters?

def _dump_dict():
..........
if val.isalnum():
text += '%s%s %s\n' % (spacing, key, val)
else:
text += '%s%s "%s"\n' % (spacing, key, val)
