test_share_links_search has unix-specific paths

[Mike McCracken]

test_filter and test_process_volumes_info fails on windows because the expected value in the code has unix paths, and the code will generate windows paths.

We need to fix the test, and verify that the code is doing the right thing - ie, is it OK to return strings with ~ on windows here?
