/src: commit with -n in release.sh scripts

Makes it possible to commit inside of /src/<package>/release.sh when
core.whitespace is set and an auto-enabled pre-commit hook
(i.e. init.templatedir is set) is used that checks for whitespace problems.

Merge pull request #170 from snaewe/sn/commit-dash-n

This pull request fixes all /src/ release.sh scripts to disregard
certain settings which would interfere with them otherwise.

It also updates our vim to version 7.4.

Thanks, Stefan Naewe!
