Including someone's address in your reply is frowned upon in this
list. http://cygwin.com/acronyms/#PCYMTNQREAIYR
I personally don't care--it's too late for the address I use on
lists and I have a very good spam filter--but other folks are very
sensitive to the issue, and rightly so.
I don't know what the list policy is for users who use only their
address and don't include their name in their "From: " header, but I
see that my mailer used your address because it couldn't find a
name. Oops.

You're welcome.

Interactive mode is the mode the shell is in when you're controlling
it from a command prompt. The shell is usually not in interactive
mode when it's executing a script.
You can get the bash-completion package from here:
http://cygwin.com/packages/
but I don't know if it installs the .bash_completion file itself or
whether you have to do that yourself. I didn't even know about it
until reading Eric's reply.

Unless you are going to use the bash-completion package which will
apparently get you this and much more, then yes, put that statement
just as it is in your ~/.bashrc. That's one of the nice things
about bash and other Unix shells: the syntax in a script file or
initialization file is the same as the syntax from the keyboard.

$- is an environment variable that contains the current set of
options. For example, from the bash I have running in an rxvt
window,
$ echo $-
himBH
You can then execute "man bash" and search for -h, for example, to
discover that the shell will "[r]emember the location of commands as
they are looked up for execution. This is enabled by default."
