[issue42980] argparse: GNU-style help formatter

[Will Noble]

New submission from Will Noble <author at will.party>:

argparse allows GNU-style long options (with '=' in between the option and the value as opposed to a space): https://docs.python.org/3/library/argparse.html#option-value-syntax

Call it pickiness, but I'd like to be able to print the help message in that format. Looking at the code, a simple refactor would be much cleaner than implementing my own custom help formatter and having to copy-paste a bunch of implementation details that are potentially subject to change in future releases. I'll submit a patch shortly.
