Ah, but virbuftest.c exposes why a return value can be useful - it lets
you know how much was trimmed, or if trimming was prevented because the
string didn't end with the suffix you expect.  Making the function
'void' would require rewriting the test, and losing out on that
functionality.  Just because all current callers outside of the
testsuite don't use that functionality (virnetsshsession.c, virsh.c)
doesn't mean we should necessarily get rid of it - is there any
alternative way to shut up Coverity to say that we can safely ignore
this return value without having to mark up all the callers?
