Yes, but you can't do it with a single "s" command. You would need to
collect all of the input into the pattern space with the N command.
This could be a problem for non-GNU versions of sed which may have a
limit on the maximum length of the pattern space.
OTOH, tr acts as a filter, writing out data as it processes it, so
there is no limit on the amount of data.

According to G_legal_filename(), ":" is legal in map names (that won't
work on Windows):
if (*s == '/' || *s == '"' || *s == '\'' || *s <= ' ' ||
*s == '@' || *s == ',' || *s == '=' || *s == '*' || *s > 0176) {
fprintf(stderr, _("Illegal filename. Character <%c> not
allowed.\n"), *s);
I'd suggest using a comma for the field separator.
