* [PATCH] add: Use struct argv_array in run_add_interactive()

run_add_interactive() in builtin/add.c manually computes array bounds
and allocates a static args array to build the add--interactive command
line, which is error-prone. Use the argv-array helper functions instead.

I should mention that I am applying to this year's edition of Google's
