I had the following in a .rhtml file that I was using for a Rails view.

The time in one hour will be <%= 1.hour.from_now %>

This worked fine.  Then I decided I wanted to comment that out
temporarily so I changed the line to this.

<!-- The time in one hour will be <%= 1.hour.from_now %-->

It complains that I have an unterminated string.

Does ERb not know how to parse HTML comments?
