Log Message:
Update to 20100430, from J.A. Neitzel in PR 43235:

1) osh globbing is now handled by the main osh process, allowing
(for example) `mkdir some_really_long_directory_name...  ; cd
some*...' and globbing for other special built-in commands as well.

2) A new, osh history-file-support feature has been added to save
the user's command-line history to the user $h/.osh.history file
if/when this file exists upon shell invocation.
