[PATCH v3 01/21] Return a copy of "master" when guessing defbranch fails

[Richard Maw]

When resolving HEAD fails or doesn't resolve to a branch
it falls back to returning "master".

This was returning a pointer to a statically allocated buffer,
which is inconsistent with every other assignment to defbranch
which are dynamically allocated.

This has not been problematic because the string is not freed.
