Because this function is static and used only by the
http-walker, when NO_CURL is defined, gcc emits a "defined
but not used" warning.

On master. I like to compile with -Werror to make sure I don't miss
warnings as the compile scrolls by.

This fix feels a little wrong, since the function isn't specific to http
support, but hopefully the comment should be obvious if we ever add
another similar commit walker that needs it.
