bug#35013: speedbar-expand-line-descendants opens non-descendant tree entries

[Kieran Barry]

Current behaviour:

speedbar-expand-line-descendants incorrectly recursively expands all nodes below the current node.

Expected behaviour:

Should only recursively expand descendants of the current node.

Steps to reproduce:

emacs -Q ~

M-x speedbar

<focus to speedbar>

<cursor over a directory that is not the last in list>

("[" is bound to `speedbar-expand-line-descendants')
