Which kind of expansion is tried is controlled by the tt(substitute),
tt(glob) and tt(subst-globs-only) styles.
There is another style, tt(completions), which allows tt(_expand) to
display or insert all em(completions) generated for the string. The use of
this is that the tags tt(expansions) and tt(all-expansions) are available,
unlike with tt(_complete).
There is another style, tt(completions), which causes tt(_expand) to
unconditionally insert all em(completions) generated for the current
word (even if the word is empty).
When tt(_expand) is called as a function, the different modes may be

Performs expansion on the current word: equivalent to the standard
tt(expand-word) command, but using the tt(_expand) completer. Before
calling it, the var(function) field is set to `tt(expand-word)'.
The tt(completions) style is also tested in the resulting context. When
it is true, the list of functions from the tt(completer) style is shifted
to remove any that would be called ahead of tt(_expand). If tt(_expand)
does not appear in the tt(completer) style, then only the two completers
tt(_expand) and tt(_complete) are used (in that order).
