#119 widgets::textarea rows and cols attributes

[CN Liou]

If both rows and cols attributes are set, the space between these two attributes is missing.

struct my_form : public cppcms::form {
    cppcms::widgets::textarea msg;
    my_form(){
        msg.message(_("Type Message Here"));
        msg.rows(2);
        msg.cols(80);
        add(msg);
    }
};

yields (note the missing space in rows="2"cols):

<label for="error">Type Message Here</label><span class="cppcms_form_input"><textarea id="error" name="_2" rows="2"cols="80"></textarea></span>

Changing line 727 for form.cpp from

        if(rows_ >= 0) {
            output<<"rows=\""<< cint(rows_) << "\"";
        }

to

        if(rows_ >= 0) {
            output<<"rows=\""<< cint(rows_) << "\" ";
        }

should be able to fix this issue.
