Hi,
The breakindent patch was originally written by Václav Šmilauer and it is
currently maintained at https://retracile.net/wiki/VimBreakIndent .
The latest version is for 7.3.944 and it can't be applied to 7.4.x.
There is an updated version by Taylor Hedberg but it also can't be applied
to 7.4.x. (https://groups.google.com/d/msg/vim_dev/JfbTedtmSuc/KIkfD9cRhgYJ)
So I have updated the breakindent patch for 7.4.x. I also fixed coding style.
There were many lines that exceeds 80 columns. And I also fixed a TODO in
strdisplaywidth(). Now strdisplaywidth() has the third parameter which can
specify a line number.
Attached patch can be applied to 7.4.035 and 7.4.050.
Regards,
Ken Takata
