I put up a new tarball: nano-2.1.9pre1 with the --quiet flag implemented as well as the syntax highlighting fixes that were committed earlier. IMO it's probably worth getting a more stable release out sooner rather than later, given that people are going to be bitten by those syntax bugs pretty frequently, at least the un-aggresive highlighting one. Anyway, it's at:
http://www.nano-editor.org/dist/test/nano-2.1.9pre1.tar.gzAssuming nothing major comes up which requires further string translation changes, I'll submit this PO file to the translators tomorrow so we can have 2.1.9 in a little over a week, and start working on the ~ syntax in .nanorcs which Eitan found in the meanwhile.
