I intend to merge back the relevant line editing changes in the next few days and wanted to provide some advance warning that this is coming. This completely replaces editline.h/cpp and makes non-trivial changes to IOHandler.h/cpp. There are also minor changes to the command interpreter. From the original commit log:</div><div class=""><br class=""></div><div class=""> Complete rewrite of interactive editing support for single- and multi-line input.<br class=""> <br class=""> Improvements include:<br class=""> * Use of libedit's wide character support, which is imperfect but a distinct improvement over ASCII-only<br class=""> * Use of "faint” colorization for line prompts<br class=""> * Breaking lines and insert new lines in the middle of a batch by simply pressing return<br class=""> * Joining lines with forward and backward character deletion<br class=""> * Detection of paste to suppress automatic formatting and statement completion tests<br class=""> * Correctly reformatting when lines grow or shrink to occupy different numbers of rows<br class=""> * Saving multi-line history, and correctly preserving the "tip" of history during editing<br class=""> * Displaying visible ^C and ^D indications when interrupting input or sending EOF<br class=""> * VI support for multi-line editing<br class=""> * General correctness and reliability improvements<br class=""><br class=""></div><div class="">The most obvious caveat here is that while these changes have been exercised on OS X, it’s certainly possible that we’ll see issues crop up on other platforms as a result.</div><br class=""><div class="">
