Remove footer from email notification excerpt

https://gerrit.wikimedia.org/r/272836

@Etonkovidova, What is the purpose of showing part of the footer? Especially if, as in the example, the footer seems to repeat info that the message header is already showing--namely the sender. (I don't see any mention of the footer in the Notifications spreadsheet. Where did this idea come from?)

The footer is automatically included (it's legally required, IIUC, hence wasn't part of the set of things we were reexamining in the spreadsheet).
This bug is about filtering out the text of footer, from their onwiki notifications.

@jmatazzoni - the footer was shown because the email body is too short. The text excerpt from email's body gets truncated to a certain length, e.g. extract two lines. In this case, email text is very short, so part of the footer was grabbed.

Thanks for he change of title @Mattflaschen. I thought this was a new feature being introduced. Now I get it!

Remove footer from email notification excerpt

It's been fixed - even if an email message is very short, the email footer is not displayed in Echo Notificaitons(or on the Notificaiton page).

If the email consists of multiple paragraphs that are very short, does the system consolidate them into one line? E.g.,

Hey There,

Thanks for the reviewing my page.

See you later man!

Should be excerpted as:

Hey There, Thanks for the reviewing my page. See...

Is that what it's doing?

That's exactly what we are trying to do.

Adding screenshots for the case with multiline emails with newline breaks.
