* keymacro.c: This module contains the procedures for maintaining

*
* An extended-key (key) is a sequence of keystrokes introduced

* el->el_keymacro.map)
* to convert these extended-key sequences into input strs
* (XK_STR), editor functions (XK_CMD), or unix commands (XK_EXE).
*
* Warning:
* If key is a substr of some other keys, then the longer
* keys are lost!! That is, if the keys "abcd" and "abcef"
* are in el->el_keymacro.map, adding the key "abc" will cause
* the first two definitions to be lost.
*
* Restrictions:
* -------------
* 1) It is not possible to have one key that is a
* substr of another.
