Maybe there's simply a bug in Emacs, but maybe you could try to set directory-abbrev-alist so that canonicalization of file names uses the symlink name rather than its target. Something like: (setq directory-abbrev-alist (("/usr/local/projects/" . "/home/jklowden/projects"))) But it seems that maybe the bug is simply that *Messages* should not use /home/jklowden/projects/csv2bin/ but /usr/local/projects/csv2bin/ (at least unless/until you set directory-abbrev-alist as above).
