I forgot to include cd-ing into the directory with spaces, though it
does not work as I would expect
/c> cd '/c/Documents and Settings'
/c/Documents and Settings/BBuchbinder> cmd /c test Hello World
c:\Documents and Settings\BBuchbinder>echo Hello
Hello
That was expected; the following is not.
/c/Documents and Settings/BBuchbinder> cmd /c test "Hello World"
c:\Documents and Settings\BBuchbinder>echo "Hello World"
"Hello World"
Shouldn't the double quotes be stripped off before cmd sees them?
/c/Documents and Settings/BBuchbinder> cmd /c test '"Hello World"'
c:\Documents and Settings\BBuchbinder>echo "\"Hello
"\"Hello
Why is the backslash being inserted to quote the second double quote and
why is the single quote being changed into a double quote? (Not that I
really care.)
