The description makes sense.  And it makes sense to show a directory
known to contain only ignored paths as just one entry, instead of
exploding that to individual files.

This sentence does not read well.  VS has no obligation to read from
"git status", so there is no "specific set of requirements" that
make us care.  If the output from "status" is insufficient you could
be reading from "ls-files --ignored", for example, if you want more
details than "git status" gives you.

The sentence, and the paragraph that immediately follows it, need a
serious attitude adjustment ;-), even though it is good as read as
an explanation of what the proposed output wants to show.

While the above description taken standalone makes sense, doesn't
the "we want all paths listed, without abbreviated to the directory
and requiring the reader to infer from the fact that aidrectory is
shown that everything in it are ignored" the log message stated
earlier contradict another change you earlier sent, that avoids
scanning a directory that is known to be completely untracked
(i.e. no path under it in the index) and return early once an
untracked file is found in it?
