Some interesting information: 1. Other vi implementations differ on how they behave here: - Elvis behaves the same way. - Heirloom vi behaves the same way. But *crashes* on some operating systems if asked to do this (it works on Ubuntu, but not Mac OSX, for me). - Most other vi implementations (nvi, vile, and Emacs' evil and viper modes) do not behave this way. 2. 2cw does _not_ delete the second linebreak, in any tested editor. 3. The POSIX vi standard specifies some distinction between 2cw and 2dw: - If there are <blank> characters or an end-of-line that precede the countth bigword, and the associated command is c, the region of text shall be up to and including the last character before the preceding <blank> characters or end-of-line. - If there are <blank> characters or an end-of-line that precede the bigword, and the associated command is d or y, the region of text shall be up to and including the last <blank> before the start of the bigword or end-of-line. (Reference to "bigwords" are because this is actually the description of the W command.) I _think_ that this is _not_ intended to imply vim's behavior, since the end-of-line is, at least in context, not a <blank>. -- -- You received this message from the "vim_use" maillist.
