Did you try \input{/home/absolute/path/commands.tex} ?

It complete crap and it could be done better :)

Setting TEXINPUTS while creating formulas makes sense to me, so I'll be
glad to have a patch for this.

The diff says you are comparing org.el and org.el.orig (the original
file).  With this method, it's easy to have the comparison done the
wrong way. 

The *really really* simple method is to use git and Emacs >=23.4.

~$ git clone git://orgmode.org/org-mode.git
 
Then open the .el file you want to edit.  When you're done editing,
simply `C-x v ='.  It will open a new buffer with the patch.

HTH,
