[PATCH] Avoid warning when From: is encoded

From: Peter Valdemar Mørch <peter@morch.com>

In commit 0706bd19ef9b41e7519df2c73796ef93484272fd $1 is used from a regexp without using () to set up $1. Later, when that value was used, it caused a warning about a variable being undefined.

The commit introduces $body_encoding and: $body_encoding = $1; which is undef.

That commit then later uses $body_encoding only here:
+ if ($has_content_type) {
+         if ($body_encoding eq $author_encoding) {
+                 # ok, we already have the right encoding
+         }
+         else {
+                 # uh oh, we should re-encode
+         }
+ }
(I removed some whitespace for readability)

.. and it was the eq that gave the warning, because $body_encoding was undefined. Perhaps a better fix is to remove $body_encoding and regexp altogether since it isn't really used. Let me know if you think so.

This is where my non-commit message goes, yeah? I'm hand editing the output of 'git format-patch'...

Junio C. Hamano commented on a previous post that I shouldn't send patches as attachments so now I'm trying git-send-email. Are there any form problems with this patch?
