  Line 111 in bfe9f59

  sed "s#$name#$value#g" "$file" >"$tmpfile" && mv "$tmpfile" "$file"

• asdf-plugin-template/setup.bash

  Line 173 in bfe9f59

  sed -i '1s;^;TODO: INSERT YOUR NAME & COPYRIGHT YEAR (if applicable to your license)\n;g' "$out/LICENSE"

3. I ran bash setup.bash but still got output containing:

And (as seen above) I've gotten files named like this (which surprised me):

$ ls . | grep "35m"
35m.gitlab-ci.yml.sed
35mREADME-github.md.sed
35mREADME-gitlab.md.sed
35mcontributing-github.md.sed
35mcontributing-gitlab.md.sed

Is this expected/desirable?
