Getting the indentation right is the default behaviour. But it can get 
rather complicated.

---BEGIN aaa.spad.pamphlet
<<*>>=
<<blah>><<foo>>
        bar
@
<<blah>>=
x
 XX
@
<<foo>>=
y
 YY
@
---END aaa.spad.pamphlet

What would you expect? Perhaps
=================
x
 XXy
         YY
        bar
=================
??? That is what I get with

notangle aaa.spad.pamphlet

Contrary to that with

notangle -L'#line %L "aaa.spad.pamphlet"%N' aaa.spad.pamphlet

I get

=============================
#line 7 "aaa.spad.pamphlet"
x
 XX
#line 11 "aaa.spad.pamphlet"
y
 YY
#line 4 "aaa.spad.pamphlet"
        bar
=============================

I know you have downloaded Aldor-Combinat. After saying "make dvi"
you find two types of .as files under the src directory.

series.as   -- generated without -L option
csseries.as -- generated with -L option.

Ignore the +++ comments since they are missing in the files that are not 
prefixed by cs.

But generally the indentation with -L is *exactly* as in the original 
source i.e. the .pamphlet/.nw file.
