Subject: Avoid composing too long "References" header.
X-Git-Tag: v1.5.1.1~20
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=a925b89cea15c90ccf131a4ec9770ca1323e4a7f;p=git.git

Avoid composing too long "References" header.

The number of characters in a line MUST be no more than 998 characters,
and SHOULD be no more than 78 characters (RFC2822).
It is much safer to fold the header by ourselves.
