It passes on Linux because, verify.createExpectedOutput creates
'RegexOutput' object with 'match_all' being false and hence it tries to
match atleast on line line in the output.
In linux
'D svn-test-work/working_copies/merge_tests-63/A_copy/D/gamma' matches our regex and hence we get the PASS.
In windows
'D svn-test-work\working_copies\merge_tests-63\A_copy\D\gamma' does not match our regex and hence we get the FAILURE.
The cause of this difference is when we author a regex we need to escape
'\' with '\\' when combined with our python escaping we need to replace
'\\' with '\\\\'.
I tried this concept in win32 box and it proves correct, Committed the
same in r26945.
Currently the notification happens from do_merge based on the revisions
we give from discover_and_merge_children. Actual decision of which range
to merge happens inside the drive_merge_report_editor. If I move this
logic to discover_and_merge_children, we can fix the notification.
But I am concerned about the following case.
Consider the case where the 'target' has mergeinfo '/src:7-10' and
'target/child' has mergeinfo '/src/child:9 (This is possible via reverts).
If we merge -r6:11 of /src,
Currently it would notify
--- Merging r7 through r8 into 'target':
--- Merging r9 through r11 into 'target':
I think the current behaviour is correct "Merging r7 through r8 into
'target'"(no-op) as it means a possible merge on child.
If we tweak this to "--- Merging r11 into 'target': ", It would be wrong
again as it does a merge of 'r6:8' on target/child.
Should we notify on each 'set_path'(non-noop) call in
drive_merge_report_editor?

Hope the explanation above answers this.
