[PATCH v4 0/3] config: add '--sources' option to print the source of a config value

From: Lars Schneider <larsxschneider@gmail.com>

diff to v3:

* pass type as parameter to "git_config_from_mem" (renamed from
  "git_config_from_buf") and "do_config_from_file"
* split current_config_type_name into two functions
* explain usage of fwrite with a comment
* use tabs instead of spaces to fix indentation error
* squash Peff's commit to split the test cases
* sort all test configs key/value pairs in the same way
* add comment to explain newline introduce by here-doc
* use real tabs for test file name
* add a test teardown
* fix hiding of git exit code t1300 and t7008
* drop "git-config.txt: describe '--includes' default behavior" patch

I like the idea of a "test set up block" within a test script. In order to clean up nicely before any subsequent tests I would like to propose a "tear down" block. Would that work as a compromise in our "test cases depend on earlier test cases" discussion?

In "t: do not hide Git's exit code in tests" I also fixed a few more places where Git's exit code was hidden. Please drop this patch if you think that this should not be part of this series.

Thanks a lot for the reviews and explainations, Lars
