rough patch

Here is a rough patch of the aforementioned change -- to look at the column of
the first non-whitespace character on the line of the guard token, instead of
looking at the column of the guard token itself.  The patch eliminates all of
the -Wmisleading-indentation false positives from the Linux kernel build, and
all of the false positives from the sqlite build.
