This time I tried to mix your approach and the current code. As a result, I
get almost no slowdown in normal conversion mode. Moreover, I used the
special loop structure to implement the KEEP_TRANS flag, so as a bonus the
code runs faster in several modes when compiled with GCC (15-20 % on my
machine). I don't think this will hurt other compilers... and GCC rules :-)
