#91049 — case-sensitive configparser without magical interpolation?

[python 2.7]
I need to use a configparser that is case-sensitive for option names, but does not do magical interpolation of percent sign.  
I.e.:

[Mapping0]
backupHost = eng%26
dbNode = v_br_node0001

should be read (and later written) as is, including capitalization and the percent sign.  

I find that RawConfigParser keeps the %, but downcases the option name.
And SafeConfigParser can be hacked with optionxform to be case-sensitive, but does interpolation.
How can I get case-sensitive but no interpolation?

RawConfigParser also has the optionxform method; have you tried overriding that?

If that doesn't work, then how strict is the 2.7 requirement? In 3.2
or later, the ConfigParser takes an interpolation keyword argument
that can be used to disable interpolation:

That worked perfectly, thanks!
