I finally sorted this out - not through intelligently working out how
the syntax should work, but by trial and error.
Check out the final result:
text =
"${sg{${lookup{$local_part}lsearch{/var/mail/sites/${domain}/.vacations}}}{\\\\\\\\n}{\n}}"
I'm unclear why I need to escape that regex with *4* backslashes for
each one I want in the final regex.
Very odd.
I'd expect once for the regex: {\\n}
And once for the initial string expansion: {\\\\n}
I'm guessing the third expansion was needed due to the whole thing being
contained in a double-quoted string constant?
