...uess similar option exists also for Mercurial) to "discard" merge tracking info in git log.
From what I understand svn:mergeinfo property stores per-path information about conflicts (Subversion is changeset-based), while in Git and Mercurial it is simply commit objects that can have more than one pa...

What is the difference between native code, machine code and assembly code?
...that it is a bit smarter about symbols. A side effect of generating debug info after generating machine code like unmanaged compilers often do.
