bash completion tests failing on windows

[Vincent Ladeuil]

Since revno 5632 (Revision id: <email address hidden>), the following tests are failing on windows (seehttp://babune.ladeuil.net:24842/job/selftest-windows/315/) :

    * bzrlib.plugins.bash_completion.tests.test_bashcomp.TestBashCompletionInvoking.test_revspec_tag_all
    * bzrlib.plugins.bash_completion.tests.test_bashcomp.TestBashCompletionInvoking.test_revspec_tag_endrange
    * bzrlib.plugins.bash_completion.tests.test_bashcomp.TestBashCompletionInvoking.test_revspec_tag_prefix
    * bzrlib.plugins.bash_completion.tests.test_bashcomp.TestBashCompletionInvoking.test_revspec_tag_spaces

This is probably caused by the change in the way we find executables.

I.e. bash wasn't found previously and the tests were skipped, now that it's found the tests fail.

I'm going to mark the tests as known failures until we fix this.

The associated branch mark the failing tests as KnownFailure and would be a good starting point for whoever want to fix the bug.

Failed to reproduce this problem. Test environment:
- Windows 7
- Bzr 2.4.0 installed from standalone Windows installer
- bash_completion plugin manually copied to plugins dir
- Bazaar directory first on the PATH, cygwin bin directory last
- bash 4.1.10(4) as installed by cygwin

All 24 tests succeed after disabling the known failure exception.

Someone who can reproduce this please give me details, particularly on where his bash.exe came from.
