[PATCH] commit-tree: do not pay attention to commit.gpgsign

ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) introduced a "signed commit" by teaching --[no-gpg-sign option and commit.gpgsign configuration variable to various commands that create commits.

Teaching these to "git commit" and "git merge", both of which are end-user facing Porcelain commands, was perfectly fine. Allowing the plumbing "git commit-tree" to suddenly change the behaviour to surprise the scripts by paying attention to commit.gpgsign was not.

Among the in-tree scripts, filter-branch, quiltimport, rebase and stash are the commands that run "commit-tree". If any of these wants to allow users to always sign every single commit, they should offer their own configuration (e.g. "filterBranch..gpgsign") with an option to disable (e.g. "git filter-branch --no-gpgsign").

Ignoring commit.gpgsign option _obviously_ breaks the backward compatibility, and I seriously doubt anybody sane is depending on this misfeature that commit-tree blindly follows commit.gpgsign in any third-party script that calls it, but following the "be careful when removing (mis)features" tradition, let's give these scripts an escape hatch. Passing the new --use-commit-gpgsign-config option to makes it pay attention to the commit.gpgsign configuration again.
