AIX sed oddity

[Ralf Wildenhues]

[ http://thread.gmane.org/gmane.comp.sysutils.automake.bugs/3946/focus=3948 ]

On AIX 5.3:
$ sed -e ''
| sed: 0602-429 No editing script was provided.
| Usage:  sed [-n] Script [File ...]
|         sed [-n] [-e Script] ... [-f Script_file] ... [File ...]

It still fails if followed by -e args that have normal script bits.
The following work as expected:

$ sed ''
$ sed -e '
'
$ sed -e ';'

Nice, huh?  OK to install this?

Cheers,
Ralf
