Message:
I'm using sed 4.2.2
I ran the following single command from bash:
sed -ne 's/^[ \t]*[Hh][Oo][Ss][Tt]\([Nn][Aa][Mm][Ee]\)\{0,1\}['"$'\t
'"']\{1,\}\([^#*?]*\)\(#.*\)\{0,1\}$/\2/p' "${config[@]}"
It said the errors.

Message:
I cannot reproduce, I get no errors when I complete with your config, so more
details are needed.
Looking at the patch, I'm confused; are you sure you got it the right way?
Turning \{0,1\} into ? and \{1,\} into + is introducing a sed portability
issue, and removing the backslash from front of ( and ) actually *introduces*
the "invalid reference \2" errors you're seeing as the unescaped parenthesis
are no longer capturing groups...?
