Noo-oo, it is cw within a word which is strange. Invoked from whitespace
it is unsurprising, going to the start of the nth word, exclusive.
Perfectly consistent with w by itself.

Please read ":help cw", which makes clear that it is deliberately
strange within a word. A mapping to provide consistent behaviour is
proffered there.

Vim has "compatible" and "nocompatible" modes w.r.t. vi. Perhaps you
might think of doing the same w.r.t. vim. Whether vi compatibility is
retained in your vim-n-a-bit, is another question. (Look at the vi bug
described at ":help cw".)

In this instance, it is already improved in Vim itself. ;-)
(Each user can choose convenience or correctness, according to
preference - that's close to perfection.)
