change default behavior of 'read' builtin in ash

[egor duda]

Hi!

  currently 'read' builtin in ash requires -e option to make it treat
backslashes as escapes. current BSD ash and SUSv2 do this by default
and use -r option to turn this special treatment off. patch attached.

after this patch, libiberty testsuite passes all test on cygwin :)

	* miscbltin.c (readcmd): Change default mode to process backslashes
	as escapes. Use '-r' option to switch to "raw" mode. '-e' option
	is now ignored.
