symlinks inside folders are not followed

[posva]

Hi, I noticed that if I create symlinks inside of a folder, they aren't followed. They do work if the target path is a symlink.

Here is a simplified reproduction

set -e

# create a temp folder to test
FTEMP=$(mktemp -d)

echo "Creating test repository in $FTEMP"
mkdir -p "$FTEMP"
cd "$FTEMP"

mkdir -p cache/pkg-1/docs
echo "The answer is 'osgrep is great!'" >cache/pkg-1/docs/file1.md

mkdir docs
ln -s cache/pkg-1 docs/pkg-1

which tree && tree "$FTEMP"

# osgrep index --path docs
osgrep search "answer" docs

echo
echo "=== Now the version that works ==="
echo

FTEMP=$(mktemp -d)

echo "Creating test repository in $FTEMP"
mkdir -p "$FTEMP"
cd "$FTEMP"

mkdir -p cache/docs
echo "The answer is 'osgrep is great!'" >cache/docs/file1.md

ln -s cache/docs docs

which tree && tree "$FTEMP"

# osgrep index --path docs
osgrep search "answer" docs

You will notice that the first scenario doesn't work but the second does.
