[PATCH v2 0/5] completion: remove hardcoded config variable names

Changes since v1:

 * Corrected my email in PATCH 2/5 (sorry for the noise)

v1: This series removes hardcoded config variable names in the __git_complete_config_variable_name function, partly by adding a new mode to 'git help'. It also adds completion for 'submodule.*' config variables, which were previously missing.

I think it makes sense to do that in the same series since it's closely related, and splitting it would result in textual conflicts between both series if one does not build on top of the other, but I'm open to other suggestions.

Thanks,

Philippe.
