please try the following:

open a file with this content:

-----cut-----
1

2

3

4

5

6
-----cut-----

now position the cursor at the beginning of line 1 and consecutively press Ctrl+Down till the end of the file.
All looks good.

Now press Ctrl+Up: but the cursor takes a break on the empty line 2.

now change the file to:

-----cut-----
1

2

3

4

5

6
-----cut-----

and place the cursor again at the first line, than do the same thing as above: downward the cursor is placed before the paragraph line and upward at booth lines, the paragraph line itself and the enlty line before the paragraph and in the empty line after the first paragraph.

last test:

-----cut-----
1

2

3

4

5

6
-----cut-----

the cursor takes now the middle of the empty lines as a 'paragraph'. and up two lines in front of each paragraph.

    first patch:

    the only change that may be not wanted is this: if the cursor is in the first line of a paragraph, but not at the beginning, a backward_paragraph() goes to the prev paragraph, not to the beginning of the current.

    second patch (actually patch series):

    patch 1: extended-paragraph.patch

    this uses a state machine like algorithm, which brings also back the lost behavior (which is imho a bug by itself) from the first patch

    patch 2: extended-paragraph-end.patch

    this extends the two functions with the "end" argument. which changes the 'jump-point' to the end of the paragraph, i.e. the first blank line after a paragraph

    patch 3: extended-paragraph-any.patch

    this extends the two functions with the "any" argument, which is mutual exclusive with the "end" argument and uses both 'jump-points' of a paragraph, i.e. the first line of a paragraph and the first blank line after a paragraph

    found a small bug, if a file has no terminating new line.
