Functions

All functions should have a grdoc header.

They should have a single place of return at the end of the function to make it easy to tidy up and work out what is going on.

Where possible variables should be declared at the top of the function with no initialisation, and then initialised after all variable declarations. Of course this can't apply to static variables, 'though these should be kept to a minimum so we can make a thread-safe version of Cactus later.
