(skeleton-newline-indent-rigidly): New variable.
(skeleton-internal-1): Use it for indenting after \n because previous behaviour was only useful for `sh-script.el' and old `ada.el'. Other modes now get their own indentation. (skeleton, skeleton-modified, skeleton-point, skeleton-regions): `New' variables for passing between the mutually recursive functions of the skeleton engine. Introduced to remove compiler warnings. (skeleton-proxy): New argument `str' to make this settable when calling a skeleton as a function. (skeleton-insert): New argument `str' to pass down. Element `\n' now usually indents according to mode. Subskeletons may also have a list of strings as iterator. Earlier modification also removed meaning of `quit' -- I did not put it back in since it's useless. When quitting out of a subskeleton while still wrapping around text don't duplicate first line of that text. (skeleton-end-hook): New hook useful say for modes that leave a `;' on an empty line to indent right and then want to clean it up when doing a skeleton there.
