Subject: teach warn_dangling_symref to take a FILE argument
X-Git-Tag: v1.6.6-rc1~44^2~3
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=3cf6134ad016712ecb78186d9079b9cff7b25416;p=git.git

teach warn_dangling_symref to take a FILE argument

Different callers of warn_dangling_symref() may want to control whether its
output goes to stdout or stderr so let it take a FILE argument.
