[issue3516] string formatting quirk using %.%

[nadav]

nadav <[EMAIL PROTECTED]> added the comment:

The main problem with this is that the following code does not make any
sense:
"%(a)%" % dict(a=3)

It has no semantic meaning (take the dictionary paramater a, and do nothing
with it).
It must be a user bug (except in very wierd cases).

I agree that when I consider the implementaion, it makes sense, but as a
python user, this behavior is really non-intuitive.

It&#39;s straightforward if you consider the implementation of the<br>
requirement that %% renders a single percent sign: the second % is<br>
parsed just like any other formatting code (i, d, f, etc.) and the stuff<br>
between the first % and the formatting code is treated completely uniformly.<br>
