- updated to 1.10
* Provide and API got accessing the original key that a value was set
with, in a case-preserving way. If the case of the key in a file
matters, it is now possible to determine.
* The 'name' value passed to the 'callback' parameter is now no longer
forced to lower-case, as a consequence.

* Multiple bug fixes concerning filters, including empty filters,
valueless keys, and applying filters to single values.
* Add "human" argument to get_all and get_regexp, to match get
* Add an add_comment method
* Add an encoding attribute, which adds the appropriate layer on file
I/O
* Enforce that all keys must have sections, as git 1.7.4.4 began doing (forwarded request 177289 from coolo)
