At first your patch cannot be applied clearly because it is in DOS 
format (carriage return before newline).  Also I cannot understand, why 
you replace tabulation with spaces. It will be fine if you will use 
indent -kr -i4 -psl -pcs for each function you change.
And your patch changes current behaviour of mcedit.  ASCII zero is equal 
to newline now.  I cannot say I like this, but you should be consistent.
Now 0 is checked in the right part of the line, but this check is 
ommited at the left.
