Yes, it's fine by me. It seems you want to ignore the case of
overlong paths but I don't mind since it's non-portable.

I'd appreciate it. I don't think there can be too much documentation
unless it starts repeating itself. I also appreciate the "EXAMPLE"
section of other manpages like strlcpy(3), strncpy(3) etc. because
these are truly essential.

I'd prefer this as well. Albeit as said I'd use strlen() and strncpy()
because for some people (not me), copying or implementing strlcpy()
seems to be unthinkable.
