OK. This makes sense now. Probably "the name" should be added before
"sh". Despite "sh" is highlighted, I was not sure what the highlight
meant.

BTW, here is the test case.

$ cat main.sh
#!/usr/bin/env bash
# vim: set noexpandtab tabstop=2:

set -v
tmpdir=$(mktemp -d)
cd "$tmpdir"
ln -s "$(which bash)" sh
export PATH=$tmpdir:$PATH
which sh
sh
$ ./main.sh
tmpdir=$(mktemp -d)
cd "$tmpdir"
ln -s "$(which bash)" sh
export PATH=$tmpdir:$PATH
which sh
/var/folders/r7/bvmh1vvx41d63snvgbdz7bl40000gr/T/tmp.LNB9vj4Xv8/sh
sh
sh-4.4$
