[PATCH] git.c: fix sparse warning

[PATCH] git.c: fix sparse warning

[Ramsay Jones]

Commit 4acc44d720 (config: add setting to ignore sparsity patterns in
some cmds, 2020-05-27) adds an external symbol definition without a
corresponding external symbol declaration. This causes sparse to
complain: "symbol 'opt_restrict_to_sparse_paths' was not declared.
Should it be static?".

In order to suppress the warning, #include the 'sparse-checkout.h'
header file, which contains the required extern declaration.

Hi Matheus,

If you need to re-roll your 'mt/grep-sparse-checkout' branch, could you
please squash this into the relevant patch.

[This is the minimum fix - but I might be tempted to move the definition
of the variable to 'sparse-checkout.c' as well.]

Thanks!

ATB,
Ramsay Jones

Sure! Thanks for catching this.
