fix multiple bugs in countprompt
1. Height off by one in the presence of meta characters at the end of the line.

The following prompt has height 2 but countprompt used to return 3.

    PROMPT="${(pl.$COLUMNS..-.)}%f"$'\n'

You can observe the effects of the bug with esc-x followed by reset-prompt.

2. Width off by one when a line is broken in the middle of a wide character.

Assuming COLUMNS=79, the following prompt has width 2 but countprompt used to return 0.

    PROMPT="${(pl.40..\u3050.)}" zsh -df

Press ctrl-r or type ls<tab> to observe the effects of the bug.

3. Width off by 1-7 when a line is broken in the middle of a tab.

Assuming COLUMNS=79, the following prompt has width 1 but countprompt used to return 0.

    PROMPT="${(pl.10..\t.)}" zsh -df

Press Ctrl-R or type ls<TAB> to observe the effects of the bug.
