[O] Regression bug in tangle/weave

[MidLifeXis at PerlMonks]

It appears that there may be a regression problem with the current tangle/weave 
process.  I used to be able to have a noweb section for the name of the file, 
another for the version of the file, and then have an autogenerated header 
section that included those two pieces of information on a single line.  
Following is an org file snippet of my bug description.

   A regression bug has surfaced in org-mode with the tangle/weave
   process mangling the following setup:

   #+begin_src perl :noweb yes :tangle testoutput.pl :shebang #!perl
   # <<generated-from>>
   print "Hello world\n";
   #+end_src

   #+srcname: generated-from
   #+begin_src text :noweb yes
   Generated from <<file-name>> version <<file-version>>.
   #+end_src

   #+srcname: file-name
   #+begin_src text :noweb yes
   ATestFile.org
   #+end_src

   #+srcname: file-version
   #+begin_src text :noweb yes
   1.2.3.4
   #+end_src

   The last it worked* was sometime in the early 7.4 timeframe.  If I
   get some time, I may do a bisect on it, although others are welcome
   to do the work required.  Timeframe is based on memory, not
   actual checking, so first a bisect needs to be done to find where
   it last worked.


*** Actual output

#+begin_src perl
#!perl

# Generated from ATestFile.org
# Generated from  version 1.2.3.4
# Generated from <<file-name>> version .
# 
print "Hello world\n";
#+end_src

*** Expected output (or at least similar)

#+begin_src perl
#!perl

# Generated from ATestFile.org version 1.2.3.4.

print "Hello world\n";
#+end_src
