[PATCH 0/9] Extend use of parse_options()

These patches spread the use of parse_options() to some more commands.
I tried to come up with a short description for every option, but
I'm not sure I fully succeeded. In particular, the option "sparse"
in builtin-rev-list.c has no description.

Michele Ballabio (9):
  builtin-verify-tag.c: use parse_options()
  builtin-write-tree.c: use parse_options()
  builtin-prune-packed.c: use parse_options()
  builtin-ls-tree.c: use parse_options()
  builtin-rev-list.c: use parse_options()
  builtin-init-db.c: use parse_options()
  builtin-checkout-index.c: use parse_options()
  builtin-fetch-pack.c: use parse_options()
  builtin-mailinfo.c: use parse_options()
