It's too late for TR1 but not for C++0X.

But this is obvious, and I don't think pointing out the obvious makes
for better documentation.

Beginning of what? End of what? The line? The word? The
sequence/input/buffer? beg/end are not specific enough, nor are they
more memorable than bos/eos, IMO. Besides, "end" is too common to make
it a namespace scoped constant, and "beg" is a word of its own with a
meaning distinct than "begin". Nope, bos/eos are it.
