Description of problem:

gpicview-0.1.9, when build with the LIBJPEG library, does not
ask user for confirmation to rewrite original JPEG file, after
this file has been successfully rotated on user request.

Version-Release number of selected component (if applicable):
gpicview-0.1.9

How reproducible:
Always

Steps to Reproduce:
No reproducer
  
Actual results:
Original image file is without user confirmation, after issuing request
to Save the file, rewritten with its rotated copy. This destroys data
when specifically not allowed.

Expected results:
Gpicview should ask user for confirmation, if the original file
should be replaced with its rotated copy or preserved and its rotated
copy used under different file name.

Additional info:

Relevant part of the code:

#ifdef HAVE_LIBJPEG
    if(strcmp(type,"jpeg")==0){
        if(rotate_and_save_jpeg_lossless(file_name,mw->rotation_angle)!=0)
            main_win_show_error(mw, "Save failed! Check permissions.");
    } else
#endif
        main_win_save( mw, file_name, type, pref.ask_before_save ); 

The 'main_win_save' will be omitted in the case, when gpicview build
with LIBJPEG library.
