bash script fails

When verifying my PGP key, I opted to go the bash script route. I copied and pasted the command that popped up in the modal, but it failed when pasted in the terminal:

```
Error in your post
-------------------

Code: 100
Name: INPUT_ERROR
Description: bad base 64 string
```

I had to end up pasting the contents in a bash script and getting rid of some extraneous newlines at the beginning of the command to get it to work correctly.

Start by reproducing PGP key verification through the modal's bash-script option, then paste its generated command directly into a terminal. Compare that command with the version that worked after removing leading newlines. Done means the copied command runs without the bad base64 error and completes verification.
