[PATCH 24/24] git-status.txt: advertisement for untracked cache

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

When a good user sees the "too long, consider -uno" advice when
running `git status`, they should check out the man page to find out
more. This change suggests they try untracked cache before -uno.

 return more quickly without showing untracked files.

 The default can be changed using the status.showUntrackedFiles
