it looks like someone tried to use '' to make a ' happen for the possessive tense of users. But that messes up the quoting:
issue-message: 'Message that will be displayed on users'' first issue'
pr-message: 'Message that will be displayed on users'' first pr'
It should be:
issue-message: 'Message that will be displayed on the first issue for that user'
pr-message: 'Message that will be displayed on the first pr for that user'
(this gets rid of the spurious quotes, but also doesn't introduce any grammatical errors)
It was a very bad impression to have a simple script designed to welcome folks be broken by default.
