Re: [PATCH] submodule update - don't run git-fetch if sha1 available

["Torgil Svensson" <torgil.svensson@gmail.com>]

Hi

Sorry for a broken patch [inserted line-feeds]. If anyone knows how to
disable that in gmail web client, please let me know.

I also tried to follow "Using msmtp to send your patches"
[http://git.or.cz/gitwiki/GitTips ] on msys/mingw/WindowsXP with the
following result (at best) from git-send-email:

"Can't call method "mail" on an undefined value at
C:/msysgit/git/git-send-email line 551."

So I would appreciate if someone that has used the combination gmail
SMTP+Windows+git-send-email successfully (cygwin,msys or "pure") to
let us know how you did it.

Best Regards,

//Torgil
