Filenames are assumed to be 8 characters plus one extension of 3
characters. Multiple dots in file names are not allowed. When this
option is on, dots in file names are replaced with underscores when
adding an extension (".~"
or ".swp"). This option is useful
when editing files on an MS-DOS compatible filesystem, e.g., messydos
or crossdos.
