Version 179 is out.

Hi all,

TXR 179 is out. Binaries at Bintray, as usual.

• Improvements in Lisp listener:
•  Line breaks can be entered with just Enter, when the syntax is incomplete (open parens, etc).
• Ctrl-X ? displays a three-page command "cheat sheet"
• Multi-line mode is now default.
• Improvements in generic sequences.
• Hardened the internals in the area of bignum integer manipulation.
• Broken sign-extend function fixed.
• Bug fixed in bitfield layout logic in FFI structs.

Cheers ...
