Bear in mind that file-accessible-directory-p works prior to
call-process being run. Call-process does something that breaks it.
Interestingly it breaks file-accessible-directory-p for *all* files in
the same directory, so
(call-process "/usr/bin/true")
(file-accessible-directory-p "/usr/bin/false")
fails, while
(call-process "/usr/bin/true")
(file-accessible-directory-p "/bin/zsh")
works correctly. (Well, call-process itself fails, but
file-accessible-directory-p works.)
I haven’t been able to work out what it is that call-process is doing
that causes this.
