+Subject: [PATCH] rc: do not share certain special vars; fix $status bug for most cases
+
+
+Certain special vars (namely $*, $pid, $apid, and $status)
+are used internally and should not be set after a child
+returns.
+
+There has been a long-standing bug where checking the value
+of $status with ~ overwrites the value of $status. $status
+is now restored in most cases, other than running it
+as a standalone built-in command.
+
+Man page for rc is updated

+	internally as a function, which then update the parent

+Subject: [PATCH] rc: keep env vars and functions in sync
+
+
+	From env(3):
+	          The env device serves a one-level directory containing files
+	          with arbitrary names and contents.  The intention is that
+	          the file name is the name of an environment variable (see
+	          rc(1)), and the content is the variable's current value.
+
+	And from rc(1):
+        Environment
+          The environment is a list of strings made available to exe-
+          cuting binaries by the env device (see env(3)).
+
+	But currently, the environment variables and functions are not kept
+	in sync with /env . For instance, '>/env/a echo -n b' will not
+	update $a to be 'b'. Also, even when the namespaces are shared
+	between processes, once the child process completes the namespaces
+	are out of sync.
+
+	This patch attempts to address that by updating the environment
+	variables and functions after children processes exit when the
+	children share the same namespace. Tests are added for the
+	functionality as well.

+Subject: [PATCH] rio: resize border and scrollbar based on font

+
+when using large fonts the scroll bar is aberrantly small, as is
+the border size. initialize the border widths and scroll widths
+based on the font size. set a minimum value based on existing
+hard-coded values.
