Make the filter_spec string a string_list rather than a raw C string. The list of strings must be concatted together to make a complete filter_spec. A future patch will use this capability to build "combine:" filter specs gradually. A strbuf would seem to be a more natural choice for this object, but it unfortunately requires initialization besides just zero'ing out the memory. This results in all container structs, and all containers of those structs, etc., to also require initialization. Initializing them all would be more cumbersome that simply using a string_list, which behaves properly when its contents are zero'd. For the purposes of code simplification, change behavior in how filter specs are conveyed over the protocol: do not normalize the tree:<depth> filter specs since there should be no server in existence that supports tree:# but not tree:#k etc. Helped-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Matthew DeVore <matvore@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
