Summary: if you do search-forward-regexp with " +", then it'll skip
all spaces. However, if you use the backward version, it'll stop at
the first space.
reading the inline doc carefully, it seems the behavior is as
specified in the doc... seems odd.
(defun xub-forward-to-space ()
"Move cursor forward to next end of space or newline."
(interactive)
(search-forward-regexp " +\\|\n+" nil t)
)
(defun xub-backward-to-space ()
"Move cursor backward to previous beginning of space or newline."
(interactive)
(search-backward-regexp " +\\|\n+" nil t)
)
Thanks.
