Magic, that works!

What I don't get is that I believe the file is removed in the 'merge'
commit 'X', which is reachable from master, not in the feature branch:

 2002 ---o----o-----o-----o-----X-----o-----o-----o--- 2011         (CDT)
                                    /
 2006 ---o----o-----o-----o--   (2009)                                  (DSF)

2f1c904 [memory] DSDP-DD -> CDT initial commit
5b47187 Migrated DSF and DSF-GDB to the CDT project.
10580b5 Updated copyright statements.
...

So 5b48718 is X, and the file exists in the DSF parent of X: c1e6da2

I think 2f1c904 is entirely wrong too -- it's another graft I've done,
to a different repo, which isn't to do with DSF, and doesn't contain
IBreakpoints.java:
 > git show 2f1c904:plugins/org.eclipse.dd.dsf.debug/src/org/eclipse/dd/dsf/debug/service/IBreakpoints.java
fatal: Path 'plugins/org.eclipse.dd.dsf.debug/src/org/eclipse/dd/dsf/debug/service/IBreakpoints.java'
does not exist in '2f1c904'

Given the file was removed during my 'merge' graft in commit X,
shouldn't it be visible  in log without --simplify-merges?

Cheers,
James
