Why can't you just use -U6 instead instead of --inter-chunk-context=3? If
this is intended for human consumption anyway, then you can just as well
increase the overall number of context lines: You get extra context lines
in the places where hunks are not fused, but this cannot be a disadvantage
for the targeted audience.
