Subject: Use const qualifier for 'sha1' parameter in delete_ref function
X-Git-Tag: v1.5.1.2~12
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1401f46bb42d1eb6225a5e08543c06a5b18fd3b7;p=git.git

Use const qualifier for 'sha1' parameter in delete_ref function

delete_ref function does not change the 'sha1' parameter. Non-const pointer
causes a compiler warning if you call to the function using a const argument.
