Previously, we used to compute and store each item's width in append_ref()
and change the ref_list.maxwidth only if we find a new maxwidth (all
within append_ref()).
Although the maxwidth variable is only needed when we use the verbose
option this is computed otherwise also (without the usage of calc_maxwidth()).
When using the merge option with verbose the maxwidth would need to be
recalculated. Hence we compute the maxwidth again using
calc_maxwidth() within the
if block.
Currently we only compute and store maxwidth if required, after
obtaining required refs.

Happy to explain.
