[PATCH 3/3] t/t4051-diff-function-context: improve tests for new diff -W behaviour

[Vegard Nossum <vegard.nossum@oracle.com>]

We now include non-empty lines immediately before (and after) a function
as belonging to the function.

We can test this new functionality by moving the "// Begin" markers on
each function to the previous line.

This commit is intentionally not part of the previous commits in order
to show that the tests do not break even when changing the behaviour of
'diff -W' in the previous commits.
