Subject: New option for "echo" utility

I have added a "-s" flag to the "echo" utility included with the DJGPP
distribution.  This flag causes the utility to echo its arguements on
separate lines.  I found a need for this when I tried to use a
librarian tool (for an embedded development system) that did not
support a "response file" type of interface for command lines that
grow too long.  It does support reading its arguments from a file
specified on the command line with "-i".  When I tried using the
standard "echo" to echo all of the commands to a file, I learned that
the dain bramaged librarian tool required that its list of files be on
separate lines.

Anyway, I have found this to be useful, so I wonder if others might
find it to be useful as well.
