Repeating the definition of a static variable seems to be valid in C.
Nevertheless, it is bad style because it can cause confusion, definitely
when it becomes necessary to change the type.
d64ec16 (git config: reorganize to use parseopt, 2009-02-21) added two
static variables near the top of the file config.c without removing the
definitions of the two variables that occurs later in the file.
The two variables were needed earlier in the file in the newly
introduced parseopt structure. These references were removed later in
d0e08d6 (config: fix parsing of "git config --get-color some.key -1",
Remove the redundant, younger, definitions near the top of the file and
keep the original definitions that occur later.

Why the heck are duplicated static variables not an error in C?
Since they aren't (as it seems), this and the next patch are just
a matter of taste.
