Changes since 4.16:
- Portability fixes. Most important: work around a never-to-be-fixed
bug in ncurses (the freely redistributable termcap/terminfo
database).
- Various minor bug fixes. Highlights:
+ use mkstemp to avoid a security loophole
+ avoid bad interaction between metakey and xterm mouse support
in windows wider than 95 characters
+ handle symlinks better
+ obscure bug in text justification that could hang JOVE
+ misuse of stat that only misbehaved on LINUX
