Update to upstream release 0.73 (security fixes)
Relevant changes taken from this...
- Security fix: in bracketed paste mode, the terminal escape sequences that should delimit the pasted data were appearing together on one side of it, making it possible to misidentify pasted data as manual keyboard input.
- Bug fix (possibly security-related): an SSH-1 server sending a disconnection message could cause an access to freed memory.
- Bug fix: tweaked terminal handling to prevent lost characters at the ends of lines in gcc's coloured error messages.
- Bug fix: removed a bad interaction between the 'clear scrollback' operation and mouse selection that could give rise to the dreaded "line==NULL" assertion box.
