* There is no -indent option to .Bd or .Bl, although you would never know that from its frequent use in this tree. There is a "-offset indent" combination that makes sense, and you can certainly say "-width indent". * Also, you can't markup the -width option argument, tho you CAN use a callable macro. So "-width Ar filename" doesn't make sense, but either "-width Ar" or "-width filename" does, as might something like "-width xxfilename" for a little extra space. * There are a lot of needlessly complex hanging tag macros in man4 used to create simple item lists. Those should be simplified one of these days before someone copies and edits yet another man4 page.
