Your specification used a period and a space after the sequence number (which is not an input line number so the awk NR variable won't work), not a tab. Try:
Code:
awk '!/^ /{printf("%d. %s\n",++n,$0);next}1' file

But after "correcting" the output you said you wanted before, you have now added an empty line in the middle of the output that the above code will not produce. (And I see no obvious reason why it should be there???)
