configure: break indentation to fix --help output

For recently added/updated options:
windows-unicode, winidn, apple-idn

It looks like the second `AS_HELP_STRING()` must start in the first
column, otherwise its indentation will appear in the `--help` output,
and break unalignment with the rest.

(There must be a better way to tackle this.)
