#Author: Matthew Elder <[e-mail]>

#make and initialize repo
hg init test; cd test;

#make a file and a symlink
touch foo; ln -s foo bar;

#import with addremove -- symlink walking should _not_ screwup.
hg addremove

#commit -- the symlink should _not_ appear added to dir state
hg commit -m 'initial'

#add a new file so hg will let me commit again
touch bomb

#again, symlink should _not_ show up on dir state
hg addremove

#Assert screamed here before, should go by without consequence
hg commit -m 'is there a bug?'
