I do ensure that paragraph styles are consistent throughout the
paragraph. New styles are applied in insertNewlineForTextView: or, if
the user changes them manually, they always cover the range of the
entire paragraph. What I am seeing is that when the user is typing in
the middle of text and I change the style after a newline, sometimes
the text indent does not update until the user types a character, at
which point the ruler and insertion point update to the correct
position. The indent seems to update find if it is larger than the
previous indent but not when it is smaller.

This works well when the user is typing at the end of the text.
When the user is typing in the middle of existing text, however,
the ruler and insertion point do not always update to reflect the
paragraph style of the typing attributes. Is this a bug? Or is this
by design? I have tried using -[NSTextView updateRuler] to force
the ruler to update but this has no effect. Is there any way to
force the ruler and insertion point to update properly?
I can't tell exactly what's going on without seeing it, but one
thing you need to keep in mind is that paragraph styles need to be
constant over the whole range of the paragraph; if they aren't, then
paragraph style fixing will make sure they are by extending the
paragraph style from the beginning of a paragraph to cover all of
it. If the user is typing in the middle of a paragraph, just
changing the paragraph style in the typing attributes wouldn't be
enough; you would need to change it for the whole paragraph in the
text storage.
