[PATCH] Removed unnecessary use of global variables.

[Erik Faye-Lund <kusmabite@gmail.com>]

git_config() now takes a third data-parameter that is passed back
to the callback-function. At the time this code was written, that
parameter did not exist, so a somewhat nasty (but by all means
correct) use of global variables was introduced. In commit
ef90d6d4208a5130185b04f06e5f90a5f9959fe3 Johannes Schindelin
<Johannes.Schindelin@gmx.de> introduced a parameter for similar
purposes.

I've changed the code to utilize this parameter to pass the
string. In addition, I've made the function calculate the string
length on usage instead, to reduce the parameters needed to what
the callback-interface supplies.
