[Doxygen-users] How to configure line-indent while using @dontinclude or @snippet

[<Eck...@t-...>]

Hello Everybody.

I use the commands @dontinclude or @snippet to insert source-examples 
into my documentation. This examples are greater sources in c, python or 
other programming-languages or parts of xml-files. The original texts 
contain a lot of indented lines what means most of the original lines 
contain more than one spaces at the beginning. But in my html-output of 
Doxygen the indention is not shown. If I use @verbinclude the original 
source format is used but unfortunately  @verbinclude supports not to 
include only parts of the text.

If you take a look to the example of @dontinclude  in the documentation 
of Doxygen (1.8.5) you will see the same effect. If you compare the 
indention of the used source to include with the included lines you will 
see there is no indention in the included lines. Thus It may be a bug.

I know that in earlier versions of Doxygen @dontinclude was able to show 
the original  indention of the included text. For example if I use 
Doxygen 1.4.x it works but since some releases I'm not able to show the 
original indention any more.

What is my mistake? Is there a parameter I have to use now? Is there 
something in the configuration-file I have to configure?
