Subject: [PATCH] [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.
