#45205: dash update

Component:  ports        |    Version:
 Keywords:  haspatch     |       Port:  dash
-------------------------+--------------------------------
 With the recent ShellShock issue there has been a suggestion that it could
 be wise to replace /bin/sh with /bin/dash instead of even with the latest
 bash version.

 This update to dash portfile brings the port to the latest release (and
 corrects the livecheck feature). Not to make it lose too much
 functionality I have it built --with-libedit, linking to the system
 libedit instead of the (obsolete) one in MacPorts. I did *not* test this
 (yet) against libedit.3.dylib .

 It could be an interesting idea to extend this (and the bash) ports
 further with a helper script that replaces the system sh (bash) with the
 port's version. I thought about adding a variant that does this, but
 realised I'd better leave that to people with a better knowledge of what
 features MacPorts provide that would detect when an Apple update had
 installed a new sh (bash) version.
