Superfluous Punctuation

So, a few weeks ago my friend Mike wrote in his blog about people using punctuation around passwords and other information that should be word-perfect.

Case in point: today I got an email at work from a lady who wanted her ContentCleanup login information changed. Here’s a direct quote from her email:

Please change my username to: minette;ihjl, and my password to:
[ommitted]

Now, she did put the password on a new line with no punctuation around it, but what about that username? Is that comma part of it, or no? Luckily, the ContentCleanup username should always be a valid email address, so this one’s bogus with or without the comma, but it’s still confusing.
