Bash diffs for better filename completion

[Curtis Galloway <curtis at pdi dot com>]

Here are some short diffs for bash in beta17.1 that make life a little
nicer.  It modifies the globbing and filename completion code to work
better with Windows' case-preserving but case-insensitive filesystem. 
It also allows running *.com files in your path.
