While it is true that this does not matter in practice (because the
context value initially comes from the end user via -U parameter that is
stored in a field of type int in diff_options structure), I agre that it
is the right thing to do to use the same type as underlying xdiff
library uses at the interface level.  From the layering point of view.
xdiff-interface.[ch] are meant to be a thin usability wrapper, it should
not needlessly deviate from how the underlying xdiff operates.
