I haven't checked what the standards say, but in practice I think it's okay. An alternative would be to do something like static const char SUBMODULE_WITH_GITDIR = "*** (submodule with gitdir) ***"; which is a bit more error-prone because attempts to use it as a string wouldn't crash. We use (void *) 1 in the same way a few places currently.
