test-git-export: add globs the test runner wants on Windows The only difference for the first two was to add the globs, but the third line of output on Windows was '..\dir2\copy'. I'm not sure why 'copy' is output on Windows instead of '*'.

run-tests: explicitly handle unicode when writing xunit file The xunit writer was passing a str to a minidom API. An implicit .decode('ascii') was performed somewhere, causing UnicodeDecodeError if test output contained non-ascii sequences. This patch converts test output to utf-8 before passing it to minidom. We use the "replace" strategy to ensure invalid utf-8 sequences get munged into �.

parsers.c: avoid implicit conversion loses integer warnings These warnings are raised by Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn) and were introduced in 539b3c7eea44

test-annotate: conditionalize error output for Windows It seems better to leave the actual output in place instead of globbing everything but 'abort:', in case it starts aborting for other reasons. It isn't clear the purpose for reversing the file name position, but that originates in windows.posixfile.

test-diffstat: add a glob the test runner wants on Windows The test gets a '~' status without it.

tests: add testing for diff.showfunc The diff.showfunc config knob did not have coverage before.
