Summary: Bug/limitation in ConfigParser
Initial Comment:
It is not possible to use '%' character in config
options in combination with $() substitution.
Example: Given this configuration file:
[DEFAULT]
option1=xxx
option2=%(option1)s/xxx
ok=%(option1)s/%%s
not_ok=%(option2)s/%%s
config.get('DEFAULT', 'ok') returns xxx/%s
but config.get('DEFAULT', 'not_ok') fails with an
exception because the '%' needs to be escaped multiple
times depending on the evaluation depth:
%(option2)s/%%s -> %(option1)s/xxx/%s -> exception
what I would like it to do is:
%(option2)s/%%s -> %(option1)s/xxx/%%s -> xxx/xxx/%s
Attached to this bug report is a simple patch to work
around this limitation (not very elegant, but it works)

I'm afraid getting this "right" is going to be much more
tedious that the proposed patch. It's unclear to me at the
moment whether this should be a documented limitation or if
we should really fix it. The ConfigParser module is
generally in bad shape, unfortunately. ;-(

Forgot the python version: this problem is present in both
python 2.1.2 and python 2.2
