No, git reports this as a merge conflict, and lets you resolve it
manually (I just tried it).

If I'm not mistaken, git's comparison and merging algorithms are
line-based.  It will see that the line has changed in both branches;
it won't see the similarities within the line.

If you split the declaration into multiple lines, so the variable name
and the initial value are separated, git will do an automatic merge.
The message I got on the merge was:

    Fast-forwarding to: a
    Trying simple merge with b
    Simple merge did not work, trying automatic merge.
    Auto-merging foo.c
    Merge made by the 'octopus' strategy.

In my experience, git is very good at doing automatic merging in most
cases, and at determining when it should let the user merge manually.
But of course it's not perfect.
