Because no flags were set for regex matching, the regex engine was
assuming that the subject string past-the-end matched a end-of-line.
As the subject string already ended with a \n character, the regex
engine processing of the "past-the-end" position would match '^$'
as ^ matched past the existing \n and $ matched the assumed
end-of-line.

Use the custom object match command for copying indentation of blocks,
rather than simply increasing/decreasing indentation when start and end
statements are encountered.
This fixes an issue where a newline added after an already correctly
placed `else` or `fi` would trigger an unnecessary deindent. Tests have
been added to ensure no regression in this behaviour.
Previously, spelling suggestions were presented with the :menu command,
requiring the user to cycle through wild and fanciful alternatives to get to the
one they wanted. Now, we present suggestions with the :prompt command, which
allows the user to type to filter down the list, and also to customise the
replacement after they've chose it (perhaps to fix capitalisation or add
apostrophe-S).
We also use the mispelled word as the initial content of the prompt. That
filters out the wildest alternatives by default, and allows the user to edit the
original word instead of forcing them to choose from among the suggestions. To
get the full list of suggestions, it's easy enough to just backspace until the
word you want appears in the list.
This adds highlighting for
- quoting operators qw, qr, and qx, like `qw< some words >`
- angle brackets after a quoting operator, like `q<string>`
- punctuation as quoting delimiter, like `q|string|`
- POD sections, which start with ^=\w and and with ^=cut
- heredocs; the marker can be a bare word, or a quoted word, like
print <<~ 'EOF'
single quoted heredoc
EOF
Closes#3736
No attempt is made to use different highlighting for interpolated (qq or
"") strings just yet. Recognizing quote boundaries is more important.
