Subject: Make letremoveunused work for recursive lets again.
X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;h=a166e4049d45e4e1688baf748e1a82806374a3c0;hp=a166e4049d45e4e1688baf748e1a82806374a3c0;p=matthijs%2Fmaster-project%2Fc%CE%BBash.git

Make letremoveunused work for recursive lets again.

The non-recursive version is also changed to work for each nested let in
turn, instead of running on a bunch of them at the same time.
