Jeff King 82ebb0b6ec add test_cmp function for test scripts
Many scripts compare actual and expected output using
"diff -u". This is nicer than "cmp" because the output shows
how the two differ. However, not all versions of diff
understand -u, leading to unnecessary test failure.

This adds a test_cmp function to the test scripts and
switches all "diff -u" invocations to use it. The function
uses the contents of "$GIT_TEST_CMP" to compare its
arguments; the default is "diff -u".

On systems with a less-capable diff, you can do:

  GIT_TEST_CMP=cmp make test

test_description='git add -u
This test creates a working tree state with three files:
top (previously committed, modified)
dir/sub (previously committed, modified)
dir/other (untracked)
and issues a git add -u with path limiting on "dir" to add
only the updates to dir/sub.
Also tested are "git add -u" without limiting, and "git add -u"
without contents changes.'
