"git submodule status" did not check the symbolic revision name it
computed for the submodule HEAD is not the NULL, and threw it at
printf routines, which has been corrected.
* nd/submodule-status-fix:
submodule--helper: don't print null in 'submodule status'
printf("%c%s %s", state, oid_to_hex(oid), displaypath);
- if (state == ' ' || state == '+')
- printf(" (%s)", compute_rev_name(path, oid_to_hex(oid)));
+ if (state == ' ' || state == '+') {
+ const char *name = compute_rev_name(path, oid_to_hex(oid));
+
+ if (name)
+ printf(" (%s)", name);
+ }
printf("\n");
