bin/169773: [libedit] Resizing causes /bin/sh to repeat edit operations

Old Synopsis: [patch] sh(1): Resizing causes /bin/sh to repeat edit operations
New Synopsis: [libedit] Resizing causes /bin/sh to repeat edit operations

Responsible-Changed-From-To: jilles->freebsd-bugs
Responsible-Changed-By: jilles
Responsible-Changed-When: Sun Sep 1 16:11:38 UTC 2013
Responsible-Changed-Why: 
The underlying problem is in libedit, not in sh.

A dirty workaround is possible in sh by setting SA_RESTART for SIGWINCH.
This prevents the repeated operations but does not apply the size change
until the next line.
