PATCH: Improve POSIX conformance in dejagnu(1)

While auditing the shell version of dejagnu-report-card for POSIX 
compliance, whether POSIX sed(1) is actually required to support using 
semicolon as a command separator seems to be unclear, but does permit 
multiple "-e" options.  The text in 
<URL:http://pubs.opengroup.org/onlinepubs/009695399/utilities/sed.html> 
seems to suggest that only newlines are valid command separators, but 
that each "-e" option effectively has a newline appended.

This patch removes the one use of semicolon in a sed(1) program in the 
dejagnu(1) multi-launcher.

ChangeLog entry:
	* dejagnu: Avoid use of semicolon as sed(1) command separator.
