Subject: 24.0.50; format function broken for zero-padded hex chars
Date: Sun, 5 Jun 2011 20:34:50 +0100

Evaluate the following expression:

(format "%06x" 176)

Expected result: "0000b0"

Actual result: "    b0"

This breaks some Slime backends, since swank packet lengths are encoded
into network messages using this method.

Some inputs appear to work fine, e.g.

(format "%06x" 95) => "00005f"

I'm using a snapshot build from emacsformacosx.com, and it's 2 or 3 days
old.

I'm taking the liberty of CCing the author.
