Add indented heredocs.
This adds a new modifier '~' to heredocs that tells the parser
that it should look for /^\s*$DELIM\n/ as the closing delimiter.
These syntaxes are all supported:
<<~EOF;
<<~'EOF';
<<~"EOF";
<<~\EOF;
The '~' modifier will strip, from each line in the heredoc, the
same whitespace that appears before the delimiter.
Newlines will be copied as is, and lines that don't include the
proper beginning whitespace will cause perl to croak.
Some examples:
if (1) {
print <<~EOF;
Hello there
EOF
}
prints "Hello there\n";
The following:
if (1) {
print <<~EOF;
Hello There
EOF
}
croaks with:
Indentation on line 1 of heredoc doesn't match delimiter at - line 2.
