test-run-tests.t: tests the --retest option

run-tests: fixes the number of tests ran when '--retest' is enabled This patch fixes a regression recently introduced by a refactoring. (see 92a6b16c9186 and about 200 previous changesets from Gregory Szorc) While retesting, that is when '--retest' is enabled, only failure tests run and others either skipped or ignored. During retesting, "result.testsRun" holds the count of failure test that has run. But as while printing output, we have subtracted the skipped and ignored count from "result.testsRun". Therefore, to make the count remain the same, we need to add skipped and ignored count before printing.

run-tests: skipped test should not produce 'i' mark while retesting When '--retest' option is enabled then skipped test should not produce 'i' mark. This fixes a regression introduced by 92a6b16c9186 and about 200 previous changesets from Gregory Szorc.

test-run-tests.t: test running a failing test

run-tests: filter whitespace at end of error diffs Python 2.6 and 2.7 produce slightly different diff headers.

run-tests: produce '!' mark after running a failing test This patch fixes a regression recently introduced by a refactoring (see 92a6b16c9186 and about 200 previous changesets from Gregory Szorc). '!' mark denotes that the test gets failed while testing.

run-tests: produce error on running a failing test This patch fixes a regression recently introduced by a refactoring (see 92a6b16c9186 and about 200 previous changesets from Gregory Szorc). It produce an error message everytime with a test filename which gets fail while testing except at one condition when '--nodiff' option is enabled.

test-run-tests.t: test running a passing test

run-tests: don't check for the mercurial library used when using --with-hg In the ``--with-hg`` case, we cannot properly infer the location of the mercurial library, so we skip the warning completely.
