[issue36371] FancyGetopt.generate_help crashes with TypeError

[SilentGhost]

SilentGhost  added the comment:

I'm not sure why you're using distutils, but two extra spaces at the end of 
string is not likely to be fixed. The module is frozen and only present in the 
tree for historical reasons.

[issue36371] FancyGetopt.generate_help crashes with TypeError

[Maxim]

New submission from Maxim :

Hi!

FancyGetopt.generate_help crashes if help text in option_table is None:

instance = FancyGetopt([('long', 'l', None)])
help_text = instance.generate_help()

TypeError Traceback (most recent call last)
 in 
> 1 a.generate_help()

/usr/local/Cellar/python/3.7.2_2/Frameworks/Python.framework/Versions/3.7/lib/python3.7/distutils/fancy_getopt.py
 in generate_help(self, header)
352  (max_opt, opt_names, text[0]))
353 else:
--> 354 lines.append("  --%-*s" % opt_names)
355
356 for l in text[1:]:

TypeError: * wants int

This code is in master branch too.

And if help_text is empty string code behavior is like a help_text is actually 
pass and added 2 whitespaces.
