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. But when I get log with -m flag for merge revision, I can't see that file in the list of changed files. Why?
