man-pages(7) is silent on how to handled lists.  the only reference i can see
is in an aside in an unrelated section:
       When enumerating a list of error codes, the codes are in bold
       (this list usually uses the .TP macro).

glancing through existing man pages, it seems that `.IP` is the answer.  but
beyond that, we only have chaos.  can we pick & document a standard here ?

for numbered lists, the tags are manually maintained, but use a few diff
styles like:
	.IP 1
	.IP 1.
	.IP 1)
	.IP (1)
	.IP [1]
	.IP 1:

there's also alternative lists that use a few diff styles:
	.IP a)
	.IP (a)

for unordered lists, there's a couple of diff bullet point styles:
	*
	\(bu
	\-
	o
	+
the * form seems to be the most dominate, but \(bu shows up a good amount.
* is a bit easier to type, but \(bu renders "more correctly" ?  *shrug*

finally there's the matter of indentation level.  3 seems to be the most
common, but there's a healthy amount of 2 in there too.
	.IP * 3
	.IP * 2
