The subversion tests used different tricks to create properly encoded URLs,
partly due to partial support for different ways of running the tests on
windows. Now we only need/support one way of running the tests on windows.
Windows URLs should look like 'file:///c:/foo%20bar' and on Unix platforms
like 'file:///tmp/baz'.
'pwd' in the test framework will on Windows emit paths like 'c:/foo bar'.
Explicit handling of backslashes in paths is thus no longer needed and is
removed. Paths on windows do however need an extra '/' compared to other
platforms.
This change makes test-subrepo-svn.t pass on windows with msys. Other tests
might need more work.
Many tests didn't change back from subdirectories at the end of the tests ...
and they don't have to. The missing 'cd ..' could always be added when another
test case is added to the test file.
This change do that tests (99.5%) consistently end up in $TESTDIR where they
started, thus making it simpler to extend them or move them around.
When the contents of .hgsubstate are stale (either because they've
manually been tweaked or partial updates have confused it), we get
confused about whether it actually needs committing.
So instead, we actively consult the parent's substate and compare it
the actual current state when deciding whether it needs committing.
Side effect: lots of "committing subrepo" messages that didn't
correspond with real commits disappear.
This change is fairly invasive for a fairly obscure condition, so it's
kept on the default branch.
