I disagree - rather than adding a sort call and changing the program's
runtime complexity, can't we just reduce the amount of lines _and_
duplication like this:

_AT_@ -89,9 +93,9 @@ entcmp(const void *va, const void *vb)
        const Entry *a = va, *b = vb;

- if(tflag)
- return sortorder * (b->mtime - a->mtime);
- else
- return sortorder * strcmp(a->name, b->name);
+ return sortorder * (tflag ? b->mtime - a->mtime : strcmp(a->name, b->name));
 }

 void


With line wrapping as appropriate.

Thanks,
Rob
