[PATCH] Char: cyclades, save indent levels
Save 3 indent levels in interrupt routine by moving the code to a separate
function. This needs to be done to allow Lindent do its work, since only 4
columns are used for indenting now and hence Lindent makes a big mess in the
code, when moves it 4*5 columns to the right.
