You get the tool bar as the info package had intended.

Arguably yes, but their function is context-dependent. For example, the
MH-E package defines the actions as mh-tool-bar-customize and
mh-tool-bar-folder-help or mh-tool-bar-letter-help where the default
actions are customize and help.

With the current tool-bar code, the behavior is inconsistent.

If one runs tool-bar-mode first, and then MH-E, one sees the one pair of
Preferences/Help buttons (the ones defined by MH-E). If vice-versa, one
sees *two* pairs of Preferences/Help buttons (the ones defined by MH-E
plus the ones defined by tool-bar).

Similarly, if one runs tool-bar-mode first, and then info, one does not
see the pair of Preferences/Help buttons since the info package does not
define them. If vice-versa, one sees the pair of Preferences/Help
buttons defined by tool-bar.

Does that help clear things up?

My patch makes the tool-bar's behavior consistent. It prevents the
default tool bar from interfering with the mode's tool bar if
tool-bar-mode is run after the mode has been initialized. I just wanted
a review and a "Please check it in" before checking it in. Perhaps Nick
Roberts? Here it is again.
