SpamSpan seems to replace linked text with email address for display

If I put in something like this:

<a href="mailto:name@example.com">email me</a>

It seems to always get rendered like this:

name@example.com

This is a problem because:

• If SpamSpan is applied retroactively, the meaning of many sentences is likely to break. For example, "Email me for instructions" would become "name@example.com for instructions"
• Many users prefer plain-language ("email me") to more detailed explanations ("email me at..."); this requires them to alter their writing style to accommodate the filter.

If this represents a fundamental limitation of the filter, I suggest altering the documentation to reflect it.
