Comment:

 This is true, the idea is to leave CPP directives intact.  When not using
 CPP it would make sense to ignore these '#' lines.  Unfortunately, at the
 time we are unlitting, we don't know whether we will be running CPP or not
 (the -cpp flag might be in the OPTIONS_GHC pragma, which can't be parsed
 until unlit is finished).  Perhaps we could do a two-pass unlit or
 something, but that sounds like too much effort.

 I doubt we'll fix this, but thanks for the report anyway.
