(cperl-style-alist): New variable, since `c-mode'

(cperl-style-alist): New variable, since `c-mode'
is no longer loaded.
- (Somebody who uses the styles should check that they work OK!)
- (a lot of work is needed, especially with new
  `cperl-fix-line-spacing').
Old value of style is memorized when choosing a new style, may be
restored from the same menu.
(cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to
Anthony Foiani <afoiani@uswest.com> and Nick Roberts
<Nick.Roberts@src.bae.co.uk>.
(`Perl doc', `Regexp'): New submenus (latter to allow short displays).
(cperl-clobber-lisp-bindings): New cfg variable.
(cperl-find-pods-heres): $a->y() is not y///.
(cperl-after-block-p): Add save-excursion.
(cperl-init-faces): Was failing.
Init faces when loading `ps-print'.
(cperl-toggle-autohelp): New command.
(cperl-electric-paren): `while SPACE LESS' was buggy.
(cperl-init-faces): `-text' in `[-text => 1]' was not highlighted.
(cperl-after-block-p): was FALSE after `sub f {}'.
(cperl-electric-keyword): `foreachmy', `formy' expanded too,
Expands `=pod-directive'.
(cperl-linefeed): behaves reasonable in POD-directive lines.
(cperl-message-electric-keyword): new cfg variable.
(cperl-electric-keyword): print a message, governed by
`cperl-message-electric-keyword'.
(cperl-electric-paren): Typing `}' was not checking for being
block or not.
(cperl-beautify-regexp-piece): Did not know about lookbehind;
finding *which* level to work with was not intuitive.
(cperl-beautify-levels): New command.
(cperl-electric-keyword): Allow here-docs contain `=head1'
and friends for keyword expansion.
Fix for broken `font-lock-unfontify-region-function'.  Should
preserve `syntax-table' properties even with `lazy-lock'.
(cperl-indent-region-fix-else): New command.
(cperl-fix-line-spacing): New command.
(cperl-invert-if-unless): New command (C-c C-t and in Menu).

(cperl-break-one-line-blocks-when-indent): New cfg variable.
(cperl-fix-hanging-brace-when-indent): New cfg variable.
(cperl-merge-trailing-else): New cfg variable.
Workaround for another `font-lock's `syntax-table' text-property bug.
`zerop' could be applied to nil.
At last, may work with `font-lock' without setting `cperl-font-lock'.
(cperl-indent-region-fix-constructs): Renamed from
`cperl-indent-region-fix-constructs'.
(cperl-fix-line-spacing): could be triggered inside strings, would not
know what to do with BLOCKs of map/printf/etc.
(cperl-merge-trailing-else): Handle `continue' too.
(cperl-fix-line-spacing): Likewise.
(cperl-calculate-indent): Knows about map/printf/etc before {BLOCK};
treat after-comma lines as continuation lines.
(cperl-mode): `continue' made electric.
(cperl-electric-keyword): Electric `do' inserts `do/while'.
(cperl-fontify-syntaxically): New function.
(cperl-syntaxify-by-font-lock): New cfg variable.
Make syntaxification to be autoredone via `font-lock',
switched on by `cperl-syntaxify-by-font-lock', off by default so far.
Remove some commented out chunks.
(cperl-set-style-back): Old value of style is memorized when
choosing a new style, may be restored from the same menu.

fixed.
(cperl-after-block-and-statement-beg): It is BLOCK if we reach lim
when backup sexp.
(cperl-after-block-p, cperl-after-expr-p): Likewise.
(cperl-indent-region): Make a marker for END - text added/removed.
(cperl-style-alist): Include `cperl-merge-trailing-else'
where the value is clear.
