It seems that code template expansion automatically reformats the inserted code. This is undesirable if:

1) The automatic formatting is not adequate or not desired for the code that is being inserted. For example consider 
the code template

    if (${selection} == null) { throw new NullPointerException("${selection}"); }

intended to insert a single-line null test. The automatic formatting causes it to be reformatted into multiple lines 
upon insertion.

2) The code being inserted is incomplete partial code (to be completed manually after insertion) and because of this 
its syntax is wrongly interpreted when reformatting.

It would be good if one could specify for each code template whether reformatting should be applied or not.
