(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.
(skeleton-insert): If skeleton doesn't fit in window, put beginning
at top before going to _ point.
(skeleton-internal-list): Rewritten so that resume: sections pertain
only to inferior skeletons and make str available there
(skeleton-read): Don't quit and remove partial skeleton when empty
string entered for outer iterator. Added implicit argument `input'.
(define-skeleton, skeleton-insert, skeleton-internal-list): Use `x
rather than backquote's (` x) or own (list 'x)
(skeleton-filter, skeleton-untabify, skeleton-further-elements)
(skeleton-abbrev-cleanup): New variables
(skeleton-proxy, skeleton-abbrev-cleanup): New functions
(skeleton-insert): Sublanguage element < must now be handled via
`skeleton-further-elements' (used only in sh-script and ada). Lisp
expressions can be quoted to ignore the return value.
(skeleton-read): New name for `skeleton-internal-read' because this may
be useful in skeletons.
(local-variables-section): New skeleton command, might go to simple.el.
