This is kind of funny right now, but I can't push this change.  The repo
integrity checks (same as for binutils/gdb repo btw) complain about Γ:

remote: *** Invalid revision history for commit dcac20a59d62c81c37250da8a35c5d81a5fd3ccf:

Apart from the fact that not allowing any UTF-8 char is a bit
awkward these days... how would you like the above to be expressed
under these rules?


Thanks,
