closes #345410: two_lines_rset, two_cols_rset, two_etypes_rset are badly named
replaced by multi_lines_rset, multi_columns_rset, multi_etypes_rset,
all taking optional 'nb' argument allowing to specify and exact count.
Bw compat is kept, usage of deprecated function updated in cw itself.
Also drop custom at_least_two_columns selector (in views.plots) since
it was the same as multi_columns_rset. Hopefuly the renaming will help
in avoid such pb...
We should now decide if we want to deprecate one_* selector in favor
of multi_*(nb=1). See note on this at then end of selectors.py
function insertText(text, areaId) {
var textarea = jQuery('#' + areaId);
if (document.selection) { // IE
var selLength;
textarea.focus();
sel = document.selection.createRange();
selLength = sel.text.length;
sel.text = text;
sel.moveStart('character', selLength-text.length);
sel.select();
} else if (textarea.selectionStart || textarea.selectionStart == '0') { // mozilla
var startPos = textarea.selectionStart;
var endPos = textarea.selectionEnd;
// insert text so that it replaces the [startPos, endPos] part
textarea.value = textarea.value.substring(0,startPos) + text + textarea.value.substring(endPos,textarea.value.length);
// set cursor pos at the end of the inserted text
textarea.selectionStart = textarea.selectionEnd = startPos+text.length;
textarea.focus();
} else { // safety belt for other browsers
textarea.value += text;
}
