Replace TAB by SPACE while keeping the text allignment

[GoogleCodeExporter]

I convert tab to space the allignement of my original file is not respected.
I understand that it convert all tab by x number of space regardless 
of the real spacing produce by the tab. Here is an exemple:
i_cd        : in std_logic_vector(1 downto 0);       -- Avec le GS1575A
    12123456                                  1123456
The tab spacing in this email is 6 but not all the tab containt 6 but 
it is up to 6.
When it replace the tab by space between i_cd and the ":" i want the 
replace by 8 space and not 12 because it containt two tab.
It is the same thing for the tab between ";" and "--" need to be 
replace by 7 space and not 12.
Maybe it can be an option of respecting the original allignement of 
the file when converting.

Please if possible increase the priority.

Just replacing all tab characters to x spaces can be done with a very simple 
editor (like the eclipse itself, just select one tab, copy, choose find/replace 
and paste your tab and then you can replace all your tabs to something else...)

If you have doxygen comments after your C++ members (for example) the current 
conversion method breaks all your indentation.

I do not plan to work on it due lack of free time, sorry. Patches are welcome.

If you would like to replace tabs to spaces in one file (or in a selection) in 
Eclipse
(After you set-up Eclipse to use spaces instead of tabs)

1. Select the text or select all in the editor
2. Cut
3. Paste
