[PicForth] Another gotcha: using exit in a macro exits the caller not the macro

[Alex Holden]

I just tripped over another gotcha (perhaps it's obvious to others but I 
didn't expect it). When a word is a macro, exit operates within the 
context of the word which calls the macro instead of in the context of 
the macro. So in this example:

: sometest -1 ;
: dosomething ;
: dosomethingelse ;
macro
: test1 sometest if exit then dosomething ;
target
: test2 test1 dosomethingelse ;

When sometest returns true, instead of exiting from test1 (ie. jumping 
to the next word in test2), picforth generates a return from test2 and 
dosomethingelse never gets called.
