Not taking indented text with fill-paragraph

[Cecil Westerhof <Cecil@decebal.nl>]

I have often some text like the folowing:

First some text which is a description of the list that follows the
text:
    item 1
    item 2
    item 3
    item 4

Sometimes you change something an you get:

First some initial text which is a description of the list that follows the
text:
    item 1
    item 2
    item 3
    item 4

When using M-q you get:

First some initial text which is a description of the list that follows
the text: item 1 item 2 item 3 item 4

But I would prefer:

First some initial text which is a description of the list that follows
the text:
    item 1
    item 2
    item 3
    item 4

Is there a way to change the behaviour of fill-paragraph?

One solution is to mark the text which is the description, before giving
M-q, but I would prefer a solution where this is not necessary. ;-}
