Huh? This is a pretty standard idiom in C codebases to check if we broke out of a loop early. Actually this change breaks the code, as this check is inside of an outer loop that doesn't reinitialize the group variable. So while the code as-is correctly checks if a group was found in the current iteration of the outer loop, after this patch it also matches a group that was found on a previous iteration of the outer loop. This is a prime example where static checker warnings can prompt wrong fixes. Frankly codacy should smart up to correctly analyze the controlflow interdependency. Sascha, please drop this patch.
