[issue12353] argparse cannot handle empty arguments

[Torsten Landschoff]

Torsten Landschoff <t.landschoff at gmx.net> added the comment:

Here is another possible patch that will catch the problem.

But this enables the fromfile_prefix_chars option for all tests checking empty and space arguments. This way a problem that occurs only without that option might be hidden.

We would need to run those tests with and without fromfile_prefix_chars.
