I tried this the first time, but as the code is currently laid out it seemed
The scrolling is achieved by putting the whole string on a different offset
and taking into account the delay and step of that offset. The less complex
and non-intrusive way to achieve padding is by appending the string itself
to the original (the same happens without the patch where half the viewport
is appended again on the line, look line 1070 on lcd-16bit.c).
The effect would be nearly the same as padding spaces at the end of the
string but it would respect the configured scrolling speed...
The patch doesn't change any default or previous behaviour. All remain as
they were with the only exception that the end of the line is padded with a
user selected string.
