This has to do with the where the interpretation of the quote marks are
read.  The -c option for bash expects a quoted command but the quotes
are being interpreted by the parent shell executing the cygstart
command.  The quotes are not interpreted by cygstart itself.

$ cygstart bash -c \'echo 1\;read\'
