[PATCH v2 0/2] ls-files: add %(skipworktree) atom to format option

["ZheNing Hu via GitGitGadget" <gitgitgadget@gmail.com>]

Add a %(skipworktree) atom git ls-files --format to indicate whether the
file in the index match the sparse specification.

v1: add %(skipworktree) atom to git ls-files format option. v2:

 1. no longer mentioned git ls-files -t.
 2. change %(skipworktree) output from "true"/"false" to "1"/"".
 3. fix the sparse-checkout docs link.

          Because sometimes we want to check if the files in the
     -    index match the sparse specification by using
     -    `git ls-files -t`, but `-t` option have semi-deprecated,
     -
     -    So introduce "%(skipworktree)" atom to git ls-files
     -    `--format` option. When we use this option, if the file
     -    match the sparse specification and removed from working
     -    tree, it will output "yes", othewise, output "no".
     +    index match the sparse specification, so introduce
     +    "%(skipworktree)" atom to git ls-files `--format` option.
     +    When we use this option, if the file match the sparse
     +    specification, it will output "1", otherwise, output
     +    empty string "".
