When handling a bad merge base we print an error, which includes the set
of good revisions joined by spaces. This string is allocated, but never
freed.

Fix this memory leak. Note that the local `bad_hex` varible also looks
like a string that we should free. But in fact, `oid_to_hex()` returns
an address to a static variable even though it is declared to return a
non-constant string. The function signature is thus quite misleading and
really should be fixed, but doing so is outside of the scope of this
patch series.
