Please report back on the pip issue to read more of the doc, about inline 
comments in
https://docs.python.org/3/library/configparser.html#customizing-parser-behaviour
like I should have before writing what I did.

[issue44892] Configparser fails when the .cfg file contains comments

Hi Terry, I didn't see your response. I think this won't be possible, taking in 
count the comment that Serhiy posted:

Maybe this is a reasonable behavior. What do you think about it?

Serhiy Storchaka  added the comment:

By default configparser does not support inline comments. "#  percentage sign 
'%'" is a part of value. If you want to support inline comments you should pass 
the inline_comment_prefixes argument.

But note that it can break parsing existing valid config files containing such 
prefixes. For example "background=#ff" or 
"path=C:\Python\bin;D:\Users\Me\bin" if use standard comment prefixes "#" and 
";". This is why it is disabled by default.

Make PR branch from main, which I used for testing. I verified issue on 3.10 
and 3.9, so we will backport.
