StGIT 0.14.3: extra space is added before e-mail on export after "stg edit"

Hi,

Funny problem. I have following export template:

Subject: [PATCH] %(shortdescr)s
From: %(authname)s %(authemail)s

%(longdescr)s
Signed-off-by: %(authname)s %(authemail)s

---

%(diffstat)s

So after "stg new", edit, "stg refres" (and any number of "stg refresh"es)
it exports OK. But once I did "stg edit patch", all subsequent "stg export patch"
will give (assuming author is me@foo.net):

From: My Name < me@foo.net>
...
Signed-off-by: My Name < me@foo.net>

Notice extra space between "<" and e-mail.

TIA
