Subject: [PATCH 09/14] merge-recursive.c: Initialise variable to suppress msvc warning
Message-ID: <4CFA91A2.9090409@ramsay1.demon.co.uk>
URL: https://gitlist.dev/e/4CFA91A2.9090409%40ramsay1.demon.co.uk

```

The msvc compiler thinks a variable could be used while
uninitialised and issues the following warning:

    ...\git\merge-recursive.c(1599) : warning C4700: uninitialized local \
        variable 'mrtree' used

In order to suppress the warning we simply initialise the mrtree
pointer variable to NULL.
