support indented here-docs

fix #38

[choroba]

Good start, I'd say. Thank you very much. But it doesn't work for me if the closing qtag isn't followed by an empty line.

{
    print <<~ '_INDENTED_';
        asdf
        asdf
    _INDENTED_
    warn "OK";
}

Also, pressing Tab still undoes any indentation inside the HERE-doc.

strange - for me it works without empty line

Do you still have issue when running
emacs -Q --eval '(require (quote cperl-mode) "/pato-to/cperl-mode.el")'
?

[choroba]

Yes, sorry for the confusion, my mistake. The Tab behaviour still needs to be fixed, but it can be probably done later.
