cmd: change suppress newline in echo command
By default the echo command emits its arguments followed by a line feed. If any of the arguments contains the sub-string "\c", the line feed is suppressed. This does not match shells used in Linux and BSD where the first argument has to be -n to suppress the line feed. The hush shell interferes with the parsing of backslashes. E.g. in the following command line quadruple backslashes are required for suppressing the line feed: for i in 1 2 3; do for j in 4 5; do echo \\\\c ${i}${j}; done; echo; done; To avoid unexpected behavior the patch changes echo to use -n as first argument to suppress the line feed.
