Is it really worth it? Aside from whether it's worth the performance hit, what is it worth, in general? I wouldn't object to someone adding the possibility of a `%B' behavior, even if I might never use it. But why would we put that into the default? I can guess why someone might want to use=20 `abbreviate-file-name', to get a file name in the mode-line or frame title - to get info about the directory. But I doubt I ever would. If there's a need for someone to see the directory then fine, s?he can add it to the frame title. But the NONdirectory part of `buffer-file-name' is the most specific part. And that part is used for the buffer name, which we have with `%b'. The nondir part should come before (to the left of) the dir part, at least for the default. If there's ever a need to see some directory info, then it would be better to use a uniquified buffer name than `abbreviate-file-name'. That is, use a `uniquify-buffer-name-style' other than `forward'. And `buffer-name' already gives us this behavior. To be clear, what's the motivation for adding a `%B' behavior? (But a priori I have no objection.) More importantly, what's the motivation for using it for the default behavior?
