So here it is. Except the first 4 patches identical with
'nd/list-files' in 'pu' and not reposted here, the rest is rewritten
using wt-status.c as the base.  Documentation and tests are missing.
Probably bugs lurking too. I just want to check if the UI makes sense.

if you want to pull and try out quickly. With this we got:

usage: git list-files [options] [<pathspec>...]

Filter options
    -c, --cached          show cached files (default)
    -o, --others          show untracked files
    -i, --ignored         show ignored files
    -u, --unmerged        show unmerged files
    -a, --added           show added files compared to HEAD
    -d, --deleted         show deleted files compared to HEAD
    -m, --modified        show modified files compared to HEAD
    -A, --wt-added        show added files in worktree
    -D, --wt-deleted      show deleted files in worktree
    -M, --wt-modified     show modified files on worktree

Other
    -C, --column[=<style>]
                          show files in columns
    -1                    shortcut for --no-column
    --max-depth <depth>   descend at most <depth> levels
    -R, --recursive       shortcut for --max-depth=-1
    --color[=<when>]      show color
    -F, --classify        append indicator (one of */=>@|) to entries

Any filter option can be combined with others. Status code is the same
with 'git status --porcelain'. In fact options -[iouadmADM] are
basically the 'git status --porcelain' with bells and whistles.
