Perfectly fine practice - we only add a <head> start tag to host some
attributes.  The </head> close tag adds literally nothing to the
document - the <body> starts as soon as you see an element that can't
belong in the head.  There's virtually no chance of a mistake.

HTML parsing is a solved problem - we have a spec that all browsers
follow, which specifies this down to the last detail.  htmldiff should
use this - there is a Python implementation in html5lib, but the spec
itself isn't hard to implement, just tedious.
