Bug#741040: devscripts: Add a switch, variable to ask debcommit to gpg-sign commits

[Gunnar Wolf]

Package: devscripts
Version: 2.14.1
Severity: normal
Tags: patch

For keyring-maint work, we gpg-sign each individual commit to the
repository. We were until now using a Bazaar repository, but as we are
switching to Git, we can no longer specify that commit messages should
be signed by default.

I usually do my keyring-maint commits via debcommit; this simple patch
solves our use case (and you see here included my ~/.devscripts
putting it in action).

Ah, and FWIW: I chose to leave the configuration variable as
"DEBCOMMIT_SIGN_COMMITS", because its meaning is in plural (always
sign the commits), but the command line switch in singular
(--sign-commit), because it only applies to the current case.
