Subject: plug a memleak when freeing io redirection in commands.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=7b1fe930bf82c034f3479334dae86b58524c268a;p=openbsd

plug a memleak when freeing io redirection in commands.
the leaked memory is actually reclaimed when the command
finishes but may grow until that happens, e.g. during
command execution.

ok phessler@.
testing sobrado@ jmc@ oga@.
