This looks good. Sorry, I just realized that my suggestion
was garbage as it only disabled the bit. It did not demote
DIE to WARN.
One final nit:
Can we be sure that 'conv_flags_eol' is only ever used for CONV_EOL_RNDTRP_DIE
and CONV_EOL_RNDTRP_WARN? Maybe a solution like that would be more future
proof?
if (conv_flags & CONV_EOL_RNDTRP_DIE) {
conv_flags &= ~CONV_EOL_RNDTRP_DIE;
conv_flags |= CONV_EOL_RNDTRP_WARN;
}

Sounds good. A "global_" like prefix is not used anywhere else in Git...
