${cutscr mess with ${color}

[pascalpoitras]

Bug summary

If I put, for example, ${color:31}+ in the second field of ${cutscr, it works great

/eval -n ${cutscr:2,${color:31}+,hello}

this return he+ as expected

However, if I add a background color, ${cutscr start to cut the color somehow:

/eval -n ${cutscr:2,${color:31,32}+,hello}

this return @0 instead of he+

Additional information

I have only tested ${cut and ${cutscr

The problem is that the comma is used as separator between count, suffix and string, and that ${color:31,32} is adding a comma.
Not easy to fix, I'm thinking about a way to use another separator (keeping the comma by default for compatibility).

There's a workaround which is working: /eval -n ${cutscr:2,${color:31}${color:,32}+,hello}
