You can padl() everything with spaces - numerics, strings... so

padl(1,3)="  1"
padl("A", 3)="  A"
padl("AA", 3)=" AA"

You'd need to calculate the max number of dots and max width of a between-the-dots segment, and then have a long enough string which would fit the padded version (with or without dots)... see if this would work:

1        "  1"
1.1      "  1  1"
1.1.R    "  1  1  R"
1.R      "  1  R"
1.R.1    "  1  R  1"
2        "  2"
03       " 03"
5.R      "  5  R"
10       " 10"
12.R     " 12  R"
A        "  A"
B        "  B"
AA       " AA"

Mmmm... the 03 is spoiling the fun. Perhaps padl(chunk, 3, "0") would work.
