X-Git-Tag: v0.99.4~48
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;ds=sidebyside;h=e205735da94f6ce44c56f6088b392ba5a3268d77;p=git.git

[PATCH] git-send-email-script - Fix loops that limit emails to unique values to be pedantically correct.

Email addresses aren't generally case sensitive in the real world, but
technically, they *can* be.  So, let's do the right thing.

Additionally, fix the generated message-id to have the right template used.
