Just a few other bits of relevance to the original topic:

style(6) says not to convert tabs to spaces.

If you know what text the bookmark will point to, make a comment on  
the line above it:
	/* C comment */
	.\" troff comment
	# rc/awk comment
Set the comment to the text of the bookmark. Then, search for the text  
of the bookmark with the appropriate comment delimiters. Easy enough.

> 16. HTML tag matching
An awk program can do this. The idea is to interpret tags as they come  
in the form of a stack:
	code			stack
	<html>			html
	<head>			head
					html
	<title>			title
					head
					html
	</b>			title		error: closing wrong tag
You can also check to see if tags make sense or bad tags are nested.  
For example, don't see <body><body></body></body> as normal, nor  
<title><b></b></title>.
