Lyx cannot import LAtex files with "\input" (include).

[Lars Gullik Bj�nnes]

 Gentlemen:
        Thanks for Lyx 1.3.4
 Like previous versions, its cannot import succesfully latex file with an
 "include" (actually \input as below.


\input {./redan_hdg.tex}   % - My standard book heading -
\pagestyle{fancy}
%\pagestyle{fancyplain}
\lhead{}
etc....


The file redan_hdg.tex contains most of the standard heading like :

\documentclass{book}
%\usepackage{amsmath,amssymbi,avant,bookman,chancery,charter,courrier }
\usepackage{amsmath,multicol,times,fancybox, fancyhdr, graphicx}  
%%,courrier,symbols}  %% REDAN


It seems that Lyx is unable to 'include" my local headings, related to 
documents class, macros, papersize etc...
Supporting this like the regular Latex, would be useful (this is common 
practice), and most likely, not a major task.

Thanks.
        Redan.
