headers with no fixes applied, but still 'fixed'

[Zack Weinberg]

In my 3.0 branch build tree I have two "fixed" headers whose only
change is to add a huge label at the top:

--- /usr/include/linux/i2c.h  Sun May  6 13:21:19 2001

This seems to go with

Applying io_quotes_def            to linux/i2c.h
Fixed:  linux/i2c.h
Applying io_quotes_use            to kafs.h
Fixed:  kafs.h

i686-pc-linux-gnu (Debian 'unstable'); I can provide copies of i2c.h
and kafs.h on request.  i2c.h contains no actual ioctl macro
definitions; kafs.h does, but they're all in the modern style.

I notice that the io_quotes_* hacks are triggering on lots of Linux
kernel headers because of

#ifndef KERNEL_VERSION
#define KERNEL_VERSION(a,b,c) (((a) << 16) | ((b) << 8) | (c))
#endif

which matches the rather lenient regular expressions in the selection
patterns.  For speed, it'd be nice if we could tighten them up.
Unfortunately, I can't think of a way to write a regexp that matches
"[A-Z0-9_]+IO[A-Z]*\( but not [A-Z0-9_]+VERSION\(".

Any ideas on either issue?
