insert-directory-adj-pos
insert-directory-adj-pos is a compiled Lisp function in `files.el
'.
(insert-directory-adj-pos POS ERROR-LINES)
Convert `ls --dired' file name position value POS to a buffer position.
File name position values returned in ls --dired output
count only stdout; they don't count the error messages sent to stderr.
So this function converts to them to real buffer positions.
ERROR-LINES is a list of buffer positions of error message lines,
of the form (START END).
