Add back in instructional text for Syndication Feeds

[hexley]

Pre 2.5 wp-admin used to say:
Note: If you use the <--more--> feature, it will cut off posts in RSS feeds.

This at least, if you read it carefully, could tell the user that "Summary" would show a hard coded summary value of text in your feeds, and using "Full text" will then either show the entire post in feeds, or break at the <--more--> mark.

I suggest new verbiage:
Note: "Summary" will hard code your feeds to x words in length. Selecting "Full Text" will show your entire post in your feeds, or break the feed at <--more-->

I am not sure which is correct, to use <--more--> or <!--more-->, in pre 2.5, <--more--> is mentioned, in 2.5 and forward, even in admin, the more button puts in <!--more-->

This needs clarification.

It doesn't do this anymore, so the text is redundant. The summary will use an excerpt if one is provided; otherwise it will be generated from the article content.
