It does a HELL of a lot more than that.  Did someone else write that
regex for you?  Do you even understand it?

But OK, now we have ACTUAL CONFIRMATION that your needs are MORE COMPLEX
than your EXAMPLES have shown.

Your comments (which MAY OR MAY NOT be introduced by ##) may be
"indented", and apparently your indentation may be tabs, or spaces, or
a mix.

That means you really do NEED a regex.  String comparisons won't work.

So, you need to "escape" the strings that you are injecting into your
regex.  I showed one way of doing that, in a previous message.  I may
have missed some special characters.  Be on the lookout for that.

Escape your strings, inject them into the regex, and then use the regex
in your awk or sed program to do your parsing.

All of the tools you need have been provided already.
