nnir very badly wants to return filenames which exist within your Gnus
mail area.  If you look at nnir-run-glimpse, it will delete lines
which do not end in digits, remove the prefix dir in which your mail
lives, and finally convert to a dotted.group.name, whereupon it will
ask nnml to cough up overview entries for those groups.  For indices
representing other structures, the result of all the preceding hackery
will merely result in nothing being available.  That is, nnir is very
Gnus-specific, and is not at all a general glimpse wrapper.
