hi, 

i hit a bug (git 1.6.1): when you transform a binary file into a symlink in one commit, the binary patch can't be used in "git apply". Is it a known issue?

reproducer: 

---------- #!/bin/sh -e

# the bug: if you transform a binary file into a symlink in one commit, # the binary patch can't be used in "git apply" # # nb: if you uncomment the "##" lines, the problem disappears # since the first patch will empty the binary file then the non-binary file # will be transformed into a symlink

rm -rf t t2 mkdir t dd if=/dev/urandom of=t/a count=10 cp -r t t2

cd t git init git add . git commit -m initial

##echo -n > a ##git commit -a -m foo ln -sf zzz a git commit -a -m foo2 git format-patch :/initial

cd ../t2 git apply ../t/*.patch

cd .. rm -rf t t2 ----------
