improved file name autocompletion

* pressing ^W in FG now deletes the entire directory component as in EB
* commands without glob patterns (eg. EW) can now autocomplete file names containing
  glob patterns
* When the autocompletion contains a glob character in commands accepting
  glob patterns like EB or EN, we now escape the glob pattern.
  This already helps if the remaining file name can be autocompleted in one go.
  Unfortunately, this is still insufficient if we can only partially complete
  and the partial completion contains glob characters.
  For instance, if there are 2 files: `file?.txt` and `file?.foo`,
  completing after `f` will insert `ile[?].`.
  The second try to press Tab will already do nothing.
  To fully support these cases, we need a version of teco_file_auto_complete()
  accepting glob patterns.
  Perhaps we can simply append `*` to the given glob pattern.
