Do the file names have to be as ugly as the macros? scottl liked moving
them to the MI conf directory, but the make a bigger mess there since
there are more files there. For ls -C in -current now:

Spot the unix-style names among these.

Some names are already too long, but most didn't shout.
FreeBSD ls is relatively stupid about tabular formatting. It produces
fixed-width columns aligned to tab boundaries. Thus a single name of
length 16 or more reduces to 3 columns of names in 80 columns of
characters (3 * 24 < 80 < 4 * 24), and a single name of length 24 or
more reduces to 2 columns of names in 80 columns of characters
(2 * 32 < 80 < 3 * 32). I couldn't find any option to control this.
gnu ls is smarter and produces 4 columns in both cases:

It apparently uses non-fixed-width columns with a minimum width of 2 between
columns (this is 1 more than aligning to tab boundaries is sure to give).
Both formats use rather too hard tabs, which make a mess when quoted
and don't even save much space when combined with spaces.
Quite often, a prefix collects all names with similar verboseness together
when they are sorted, so ls could be even smarter and try to keep verbose
names in wide columns, and start new columns as necessary for this, giving
ragged column depths. Next, it could sort all the verbose names into a
verbose column, or better yet, filter them out :-).
