Bug#1032812: Allow user to influence Content-Transfer-Encoding

[Dan Jacobson <jidanni@jidanni.org>]

Package: reportbug
Version: 11.6.0
Severity: minor

Allow user to influence Content-Transfer-Encoding.
Don't just leave it up to the whims of the program.

$ < /dev/null HOME=/dev/null reportbug ca-certificates --template|grep Encoding
Content-Transfer-Encoding: base64
$ < /dev/null HOME=/dev/null reportbug reportbug       --template|grep Encoding
Content-Transfer-Encoding: 7bit

For instance, the user might want a template readable by another
program, without needing to add a decoding checking step.
