In cp, are FLAG_r and FLAG_R always equal to each other?

[chrishappy]

For cp, the help text reads:

    -R       Recurse into subdirectories (DEST must be a directory)
    -r	       Synonym for -R

Then, on line 193, we see both flags being used:

Line 193: if (!(flags & (FLAG_a|FLAG_r|FLAG_R))) {

Then on the following three lines, only one r flag is being used.

Line 147: if (S_ISLNK(try->st.st_mode) && (flags & FLAG_d)) flags |= FLAG_r;
Line 245: && (try->parent || (flags & (FLAG_a|FLAG_P|FLAG_r))))
Line 467: toys.optflags |= FLAG_d|FLAG_p|FLAG_R;

Is the use on L193 redundant? Or is there a bug on the latter three lines of code?
