Can you elaborate on why you feel this reduces readability? I think it
is a slight readability improvement: keeping the redundant "if" check
suggests that the code is prepared to handle a NULL `name1', whereas
that is not the case. By removing the "if", it makes the code's
assumption (that name1 is non-NULL) more clear. A similar line of
reasoning applies to the tab-complete change.

As for "robustness in the face of future change", I don't see how it
makes any difference. The code presently assumes that `name1' is
non-NULL. If that changes, references to `name1' will need to be
checked, but that is neither difficult nor unexpected if you change the
range of values that can be assigned to `name1'. Or would you have us
add redundant "if (var)" checks before using any pointer variable, on
the principle that at some point in the future the code might change so
that the variable could be NULL?
