Hi Duke,

strictly speaking, it's probably cmd.exe's fault, as it is similar
but not identical to shell behaviour. While I/O redirection works
the same way with <, >, 2>, cmd.exe does not do globbing, i.e.
expansion of wildcard patterns. Instead it passes the arguments
straight to the program handling them. Also, AFAIR it only uses
" for quoting, not '. powershell might show different behaviour.

So I'd expect that csi did not receive 

        a.*c
        A

as commandline arguments but

        'a.*c'
        A

which would not match the input you've provided.

Write a program echoing its commandline arguments to stdout
and then feed it with different types of arguments:

csi -ss echo.scm a b A 123 a.*c 'a.*c' "d e f" 'g h i' j\ k

to test which of your assumptions with respect to arguments hold.

HTH,
