Bug#452674: Patch looks okay

["brian m. carlson" <sandals@crustytoothpaste.ath.cx>]

tags 452674 + patch
kthxbye

I know C pretty well (it's my best computer language), and the patch 
looks good to me.  The only change I would make (and this is a minor 
nit) is to cache the result of strlen by putting it into a const size_t 
variable, which may improve the compiler's optimizations.  But I think 
the patch works fine the way it is, although I haven't personally tested 
it.
