The old entry mapped the email address `<compnerd@compnerd.org>` to user name
`Saleem Abdulrasool` and email address `<compnerd@compnerd.org>`. Since the two
addresses are identical, that's a needless detail.
The new entry just maps email address `<compnerd@compnerd.org>` to user name
`Saleem Abdulrasool`.
No behavior change.

Only one person committed with these email addresses, so there's no need to use
