* skip_optional_lf() decl is old-style -- please say

	static skip_optional_lf(void)
        {
        	...
	}

* t9300 #14 fails, like this:

* expecting failure: git-fast-import <input
fatal: Branch name doesn't conform to GIT standards: .badbranchname

Subject: [PATCH] fastimport: Fix re-use of va_list

The va_list is designed to be used only once. The current code
reuses va_list argument may cause segmentation fault.  Copy and
release the arguments to avoid this problem.

While we are at it, fix old-style function declaration of
skip_optional_lf().
