bug#21535: 25.0.50; vc-follow-symlinks=ask is ineffective for directory links

[Glenn Morris]

Maybe:

cd /tmp
mkdir git
cd git
touch 1
git init
git add .
git commit -m "c1"
cd /tmp
ln -s git/1
ln -s git git2

emacs -Q /tmp/1
 -> "Symbolic link to Git-controlled source file; follow link?"

emacs -Q /tmp/git2/1
 -> no prompt

I don't think I see why that matters though, so maybe not the right example.
