1. Use double quotes to preserve adjacent spaces correctly …

   I used this action as part of a workflow to add code formatted blocks.
   Using the guide in the readme I, adjacent spaces where not correctly
   preserved, i.e. the following
   ```
         - name: yolo
           id: get-comment-body
           run: |
             echo "\`\`\`" > tmp/comment.md
             echo "+--------------+" >> tmp/comment.md
             echo "|This is a test|" >> tmp/comment.md
             echo "+--------------+" >> tmp/comment.md
             echo "|     yolo     |" >> tmp/comment.md
             echo "+--------------+" >> tmp/comment.md
             echo "\`\`\`" >> tmp/comment.md
   
             cat tmp/comment.md
   
             # https://github.com/peter-evans/create-or-update-comment#setting-the-comment-body-from-a-file
             body="$(cat tmp/comment.md)"
             body="${body//'%'/'%25'}"
             body="${body//$'\n'/'%0A'}"
             body="${body//$'\r'/'%0D'}"
             echo ::set-output name=body::$body
   
         - name: Create or update comment
           uses: peter-evans/create-or-update-comment@v1
           with:
             body: ${{ steps.get-comment-body.outputs.body }}
             issue-number: ${{ github.event.pull_request.number }}
   ```
   produced this
   ```
   +--------------+
   |This is a test|
   +--------------+
   | yolo |
   +--------------+
   ```
   Adding the double quotes around `set-output` fixed this:
   ```
   +--------------+
   |This is a test|
   +--------------+
   |     yolo     |
   +--------------+
   ```
   Further I added double quotes also around the initial `cat`, because of
   this comment https://github.community/t/set-output-truncates-multiline-strings/16852/5
   > Here are a few observation. First, it is important to suppress word-splitting upon expansion in bash. This is easiest done by enclosing with double quotes:
