When printing references that are updated during a fetch, we also print
a short summary of what is happening. This summary may either be a word
like "[up to date]" or "[rejected]", or the abbreviated old and new hash
on a reference update.
As the abbreviated hashes may have different lengths in order to be
unique we thus need to precompute the width of the summary's column by
iterating through all the objects. This is done in two locations: once
to compute the width for references that are to be pruned, and once for
all the other references. Consequentially, it can happen that the width
as calculated for these sets of references is different.
This isn't really a huge issue, but it is a bit confusing when reading
through the code. Furthermore, the current way of passing through the
summary width is rather verbose.
Refactor the code to compute the summary width once when initializing
the display state. Like this, the width will be the same and we have to
pass less variables around.
