-/* PROBLEMS/TODO:
- *
- * Only tested under Linux;  needs to be ported.
- *
- * When running mc -c under the Linux console, mc does not recognize
- * mouse clicks, which mc does when not running under fep.
- *
- * Pasting selected text containing tabs is like hitting the tab character,
- * which invokes readline completion.  We don't want this.  I don't know
- * if this is fixable without integrating fep into a terminal emulator.
- *
- * Echo suppression is a kludge, but can only be avoided with better kernel
- * support: We need a tty mode to disable "real" echoing, while still
- * letting the inferior think its tty driver to doing echoing.
- * Stevens's book claims SCR$ and BSD4.3+ have TIOCREMOTE.
- *
- * The latest readline may have some hooks we can use to avoid having
- * to back up the prompt.
- *
- * Desirable readline feature:  When in cooked no-echo mode (e.g. password),
- * echo characters are they are types with '*', but remove them when done.
- *
- * A synchronous output while we're editing an input line should be
- * inserted in the output view *before* the input line, so that the
- * lines being edited (with the prompt) float at the end of the input.
- *
- * A "page mode" option to emulate more/less behavior:  At each page of
- * output, pause for a user command.  This required parsing the output
- * to keep track of line lengths.  It also requires remembering the
- * output, if we want an option to scroll back, which suggests that
- * this should be integrated with a terminal emulator like xterm.
