less: rearrange detection of non-regular files
Move the code to detect non-regular files to the point where the
file is being opened. If num_lines == READING_FILE guarantees
that the file is regular.
Detect when a file becomes unreadable between it first being opened
and the call to update_num_lines. Mark the file as being non-regular
so we don't try that again.
