Agreed that it belongs in a separate patch.

But I'm glad you brought this up as it reminds me of the need to watch  
out for those characters which have special meaning for  
list_and_choose().

Excellent catch. Crazy old perl; I didn't realize that "0" (the  
string, not the number) would evaluate to false.

Will send a separate mail with a revised, squashed patch with these  
changes:

- "s/the first/the uniquely/" in the commit message as you suggest

- filter out prefixes which contain characters with special meaning  
for list_and_choose()

- check "defined $prefix" rather than just "$prefix"

- also fixes a problem discovered while playing with this; it didn't  
play nicely with untracked files

Cheers,
