You don't need to count spaces. Just '].*/$' would suffice. We already
know we want to start with the first ] character on the line, no matter
how many spaces follow it.
I really question the usefulness of colorizing the directory names,
but since we're already this far down the rabbit hole, we might as
well light some dynamite to make the hole deeper. I'm sure it's safe!
We're using GNU grep for coloring, so we can also use its PCRE syntax
to do "lookbehind" voodoo:
tree --du -Fh /usr/local | grep --color -P '(?<=]).*/$'
which means "start matching after a ] but don't include the ] in the
match".
