Subject: renderline: fix rendering bug when a TAB wraps.
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=bd4153a0929188ed786c8b40b3814c32d7b43109;p=edlib.git

renderline: fix rendering bug when a TAB wraps.

If a tab wraps, we show the character immediately before the tab at the
start of the next line, which is wrong.
It is particularly weird when that char is the '>' at the end of an
attribute marking.
