The only index.m I have on my computer is

/usr/share/octave/3.0.1/m/strings/index.m

The file implements function
octave:1> help index
 -- Function File:  index (S, T)
 -- Function File:  index (S, T, DIRECTION)
  ...


     See also: find, rindex.

/usr/share/octave/3.0.1/m/strings/index.m

This file is obviously in the octave's path.

yet it is not executed at startup, otherwise I would get
a a message

Invalid call to index.  Correct usage is:

 -- Function File:  index (S, T)
 -- Function File:  index (S, T, DIRECTION)

(which I do not).

Having index.m that looks like:

1

(I.e. it just a line with number 1 on it)
I get:

So I am really baffled.
