Subject: [BUILTIN] Fix CTLESC clobbering by read(1)

The changeset 55c46b7286f5d9f2d8291158203e2b61d2494420

	[BUILTIN] Honor tab as IFS whitespace when splitting fields in readcmd

uses CTLESC to prevent field splitting in read(1).  However,
it did not escape CTLESC itself in the input stream.  This patch
adds the necessary CTLESC characters so that CTLESC isn't corrupted.
