That is a valuable example for us to learn from. Right off the bat I
wouldn't have
though to indent that way, but would have noticed quickly enough when I didn't
account for the case! There were 276 blocks corrected.

Here is the final version with a tweaked regex and removed and removal
of my original replacement desire.

Thank you Nicolas.

if you are unfamiliar with that indent-to bit, here is ax example of
what it handled correctly:
