As discussed several months ago and as announced in the release notes,
the development version of Cactus now uses a slightly different naming
scheme for output files. This affects files written with the
"one_file_per_group" option.

Previously, Cactus would separate group and variable names in the file
name by two colons "::". This was not a good choice, since colons in
file names often have a special meaning, e.g. for rsync or scp,
requiring backslashes to quote these colon characters. In Windows and
in at least one cloud-based storage system, colons are not allowed in
file names. We thus think that using colons was a bad choice, and this
should not be the default setting.

Cactus now follows the Unix convention of separating different parts
in file names with a single hyphen "-". For example, the file name
"wavetoy::phi.x.asc" now becomes "wavetoy-phi.x.asc".

This naming scheme is defined by the parameter
IO::out_group_separator. You can restore the old behaviour by setting
this parameter to "::".
