The 'more' tag is not taken into account on the generation of the RSS feed. Even worse, the tag is just present in the middle of the text.

I propose a setting somewhere,

• either to allow full articles to be part of the RSS feed (and filter out the 'more' tag)
• or to allow only the text until the 'more' tag
• or to put a number of characters in (and filtering the 'more' tag in any case, should the number of characters be longer then the position of the 'more' tag.
