I've just run into this:

    (gdb) target remote | foobar
    (gdb) error starting child process ' foobar': 
          CreateProcess: No such file or directory

Note the leading space before 'foobar' in the error message. That might 
suggest that space between "|" and program name is the problem while it's 
not.

This patch fixes the error message. OK?
