Draft: Rename "Bi-directional text rendering" option
Since commit 8ad28a12, the bidiEnabled option is also used to group characters by script for rendering purposes. A comment at bug #401094 proposed to rename the option, but this never happened.
The renamed text is mostly taken from mlterm's manpage, which has the following option: -C, --ctl(=bool) Enable complex text layouting on UTF8 encoding to support indic scripts and RTL (right-to-left) languages such as Arabic and Hebrew. The default is true.
