           Summary: Suggestion of change in process for "dispatch the

This is pertinent to http://www.w3.org/TR/2011/WD-eventsource-20110310/,
"Server-Sent Events"

In the section "Interpreting an event stream" under "dispatch the event," would
it not be better to switch numbers 1 and 2 around?  Seeing that we want to
abort on the empty string, if the only data in the string is LF, it would be
stripped by step two, thus dispatching a MessageEvent with the empty string as
its data anyways.

Currently, the lines are as follows:
1. If the data buffer is an empty string, set the data buffer and the event
name buffer to the empty string and abort these steps.
2. If the data buffer's last character is a U+000A LINE FEED (LF) character,
then remove the last character from the data buffer.

I would suggest:
1. If the data buffer's last character is a U+000A LINE FEED (LF) character,
then remove the last character from the data buffer.
2. If the data buffer is an empty string, set the data buffer and the event
name buffer to the empty string and abort these steps.
