Currently the cleanup code looks like this:
free resources
return 0;
error_out:
free resources
return -1;
Avoid duplicating the "free resources" part by keeping the return
value in a variable and sharing code between the success and
exceptional case:
ret = 0;
out:
free resources
return ret;
Noticed in the svn-dump-fast-export project, where using the error()
macro in void context produces a warning.
