That sounds like a good idea, although perhaps a little bit too much like
guessing what you want to do and doing it for you (isn't there ls -1 for
that?). I think the best way to handle this is to re-arrange the G_ls*
functions in lib/gis/ls.c to do whatever we need, and make lib/gis/list.c
use them. I already have a prototype working which does both the 1-column
output and Markus's preferred ordering, but am trying to decide if it's
worth adding an argument to some of the G_ls* functions to say how many
items to print per line, or if it should always be determined
automatically. The only thing I can think that a perline option would be
useful would be if you wanted 1-column output for this sort of thing - if
we made that automatic depending on where stdout was going might that be
