I have a question about log command.
Probably I'm just missing something but anyway.
I can illustrate the question on the repository of Git.
Let's look at revision 1ed91937
It is a merge based on pair of revisions a9572072 and 294c695d.
According to blame these parent revisions have different content for
delta.h file.
I'm not sure what you mean by this statement; what blame command did
you run?
But when I get log with -m flag for merge revision, I can't see that
file in the list of changed files.
Why?
The contents of 'delta.h' is identical in both parents of that merge:
$ git diff a9572072 294c695d delta.h
$
# no difference
So 'git log -m' does the right thing by not showing 'delta.h'.
.
But blame shows different results:
git blame a9572072 delta.h
git blame 294c695d delta.h
blame does not at all claim those two revisions have different
versions of delta.h:
$ diff -u <(git blame a9572072 delta.h) <(git blame 294c695d delta.h)

It does say that _how_ those two arrived at the *same* version of the
file differed, but if you compare the portions of the differing lines
corresponding to the actual file contents you see that they are the
same...just as SZEDER pointed out.
Now I see. I just was confused about changing code ownership without
changing code. Thanks!
