because it confuses gtk-doc and breaks some links. Also change the
"Index of new symbols in GIMP 2.x" sections to be what seems to be the
modern standard (looked at the GLib and GTK+ docs), and update some
other stuff.
Single newlines in procedure descriptions are still considered normal
spaces. But 2 newlines are transformed into 1 newline. 3 newlines into
2 newlines. And so on.
This allows for a start of nicer output in the procedure browser or C
file comments (and consequently in generated html doc).
namely ellipse_select(), free_select(), rect_select() and
round_rect_select() because they are fully replaced by the new
gimp_image_select_foo() functions. Will deprecate the rest as soon as
I have figured how to put the parameter overkill of the remaining
functions into context properties.
