alias bugfix for testing in 'theedge'

[Auke Kok]

Hello everyone,

I've just committed a bugfix that apparently is an adequate fix for the 
'alias' problem causing an infinite loop during a 'lunar update' or 
'lunar fix'. I would appreciate anyone who is experincing this problem 
to 'lin theedge' and try to break it. If it still breaks, and you are 
sure you run the latest 'theedge', please send me the output of the 
command that displays the looping with extended debugging (preferably 
-vddd - 3 d's) directly to me by email - not the list.

Of course, I'd also like to hear from you if it fixes the bug for you ;^)
