test-run-tests: pad the failure test to preserve the run order Test size seems to dictate the order in which the tests are run, and the next patch will add to test-success.t. Similar to c0cecc153d25.

run-tests: prevent a (glob) declaration from reordering (?) lines Previously, if a series of optional output lines marked with '(?)' had a (glob) in one of the first lines, the output would be reordered such that it came last if none of the lines were output. The (re) declaration wasn't affected, which was helpful in figuring this out. There were no tests for '(re) (?)' so add that to make sure everything plays nice.

py3: use pycompat.byteskwargs() to convert opts to bytes We have converted opts to unicodes before passing them.

test-check-code: do not use xargs We have too many files, and passing them via arguments could cause strange errors on some platforms [1]. Since check-code.py can now take "-" and read file names from stdin, use it instead of xargs to avoid the argv size limit.

check-code: use "-" to specify a list of files from stdin This will be used by the next patch.

perf: add historical portability for util.timer util.timer has been introduced in ae5d60bb and used in perf.py since 22fbca1d. For historical portability, forcibly define util.timer in perf.py

diff: add --binary option for git mode diffs This patch adds --binary option to `hg diff` and `hg export` to allow more control about when binary diffs are displayed in Git mode as well as some tests to verify it behaves correctly (issue5510).

patch: make diff in git mode respect --text option (issue5510) This changeset makes patch respect -a/--text option in --git mode by aligning its behaviour with git itself.
