stg mail --compose is not setting In-Reply-To or Reference from the cover letter.

[chaudron]

When I use stg as follows:

stg email send --to [email protected] -a --annotate -v 3 --compose

The cover letter generated/sent is not the first email, where the rest references too. It's sent as a stand-alone email. Here is an example, see the missing In-Reply-To on PATCH 1/8, and the In-Reply-To to PATCH 1/8 in PATCH 2/8:

$ stg email send --to [email protected] -a --annotate -v 3 --compose
