I noticed that all but one can be dealt with with
perl -p -i -e 's/status_printf_ln\((.*), ""\);/status_printf($1, "\\n");/'
That is,
- status_printf_ln(s, GIT_COLOR_NORMAL, "");
+ status_printf(s, GIT_COLOR_NORMAL, "\n");
which does not look _too_ bad.
There is one instance that needs this, though.
- status_printf(s, color(WT_STATUS_HEADER, s), "");
+ status_printf(s, color(WT_STATUS_HEADER, s), "%s", "");
