what about:

  void G_ls(const char *dir, FILE *stream, int singlecolumn)

where singlecolumn is boolean: 0 prints column output, 1 prints one file
per line.

I can think of one place it might be useful, "i.group -g".


I don't like "int multicolumn" as it might be mistaken to mean number
of columns, not a boolean switch. (which is another idea, -1,0 means
auto, otherwise as specified)
