I guess that a commit-comment would still be needed, but I think that a
more conventional approach could make it all clearer:

- memset(ve->name, ' ', 16);
- if (name)
-	strncpy(ve->name, name, 16);
+ int l = strnlen(ve->name, 16);
+ memcpy(ve->name, name, l);
+ if (l < 16) /* no null-termination expected when all the space is used */
+ 	ve->name[l] = '\0';

Cheers,
Gal
