>Description:
line="// line comment /* block comment */"
printf '<%s>\n' "${line%%/\**}"
The %% should remove the longest suffix after "/*", since the first
asterisk is escaped. Bash and Ksh do it as expected, NetBSD's /bin/sh
doesn't. It removes everything after the first "/", whether or not that
is followed by a "*".

Duplicate of PR bin/53754.
(The reproduction test case is different for the
`line' initialization but the behaviour of sh(1)
is the same, i.e. with -current sh(1):

Roland, feel free to reopen it or bin/53754 if
this is not the case!)
