Yes.  I realized that previously, but since it's a GNU extension rather
than part of the C standards, I discarded that idea.  Calling

    git grep strchrnul

shows, however, that it _is_ used plentifully already.

That would, indeed, favor the current proposal but with strchnul.

Still worth thinking about whether there is no better name than slash
for something that indicated the end of the current path name segment.
