Thanks for the advice; I should block some time to fully grok shell escapes. Even with single quotes, sed still requires escaping parentheses, + operators, and other operators that would otherwise be interpreted literally (but not all operators should be escaped). In the languages that I learned regexes this wasn't required.

There's a command line switch -E for sed that gives you what we think of as "normal" regex escaping.

  You have saved me many hours of future command line hacking. Thanks!
