min vs umin for size

[ruv]

Why do you use min but not umin in the code like the following:

: name, ( a u -- ) #name min dup c, tuck move, offset, ;

Here min protects against too long u, but not from negative u (or very long positive ;).

Sorry, just sloppiness. It really should be umin. But I suppose it doesn't matter much, because strings rarely are that long.

Yes, strings themselves are usually not so long. Negative length can be result of a bug in calculations with address arithmetic.
