Unfortunately I don't find those all to be true at all. For reference, here are some examples of entries that I have:

62.88.40.141 - - [09/Jan/2008:03:45:10 -0800] "GET /core_level.cgi?cor
+e=1 HTTP/1.1" 302 83 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows 
+NT 5.1; .NET CLR 1.1.4322)" "62.88.40.141"
 (call this a normal-ish request)
10.16.0.2 - - [09/Jan/2008:02:20:39 -0800] "GET /home/eval_load.cgi?50
+" 200 2 "-" "-" "10.16.0.2" (no version)
10.16.1.3 - - [10/Jan/2008:02:18:58 -0800] "GET /" 200 752 "-" "-" "10
+.16.1.3" (no version, no ?, and nothing after the ?)
10.16.0.2 - - [19/Jan/2008:03:45:06 -0800] "GGG99994" 200 752 "-" "-" 
+"10.16.0.2" (here we have no method, no discernible request, and no v
+ersion)

Hence the need to figure out how to detect what is there.
