[issue19461] RawConfigParser modifies empty strings unconditionally

[R. David Murray]

R. David Murray added the comment:

A configurable option is probably the only way forward, due to backward compatibility reasons, but Łukasz will know for sure.  If so, it can only go in the *next* version of Python, and while we haven't hit beta yet on 3.4 it may be too late for anyone to have time to get it in before then.

Also, I was under the impression that 'key=' was the canonical way to indicate an empty value in an ini file.  As you say, the format is not well defined (no surprise).
