Berthold Stoeger 429230ced1 saving: fix resource leak found by coverity
fp_get_data() returns a copy of a string that must be freed.
Fix this in save-git.c. The analogous function in save-xml.c
has already been fixed. However, change the code to be more
idiomatic: since we own the pointer, make it "char *" instead
of "const char *". Then we don't have to cast on free().

Ultimately, we really should change string manipulation code
to C++.
