I also was bothered by this behaviour, so I wrote a patch to fix it. It
behaves better, I think, with word skipping. It adds new action routines
forward/backward_same(), where same refers to character classes, of which
there are: letters/digits/_, other graphic characters, control characters,
spaces, newline, other ascii characters; then delimiters. The
forward/backward_same() routines skip over a contiguous sequence of characters
of the same class. A "skipblanks" argument allows blanks next to the skipped
characters to be skipped too in the current direction. When bound to
ctrl-[shift-]right/left, you do have to hit the keys more often to skip words,
but you do get to stop at line ends etc.

You can find the patch here:
