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.
