The modification was introduced by b40d397b1, which is Martin's.

I don't see any reason why it shouldn't be done in both routines, as proto_item_set_end() is just "set the length to a value calculated from the specified end offset and the tvbuff into which it's an offset" rather than "set the length to this value".  I changed it to do so in 548bf927d427723ad22e8e23186a63a63e4abf43 in the master branch.
