#-
# Some information on tests:
# The bksl-nl tests deal with how \newline is handled in various situa-
#  tions. The first group of tests are places where it shouldn't be col-
#  lapsed, the next group tests are places where it should be collapsed.
# In history - Not tested yet:
#	- commands in history file are not numbered negatively
#  (and a few hundred other things)
#  You may also want to test IFS with the script at
#  http://www.research.att.com/~gsf/public/ifs.sh
# Read - To test:
#   POSIX:
#	- if no -r, \ is escape character
#	    - \newline disappear
#	    - \<IFS> -> don't break here
#	    - \<anything-else> -> <anything-else>
#	- if -r, backslash is not special
#	- if stdin is tty and shell interactive
#	    - prompt for continuation if \newline (prompt to stderr)
#	    - a here-document isn't terminated after newline ????
#	- remaining vars set to empty string (not null)
#	- check field splitting
#	- left over fields and their separators assigned to last var
#	- exit status is normally 0
#	- exit status is > 0 on eof
#	- exit status > 0 on error
#	- signals interrupt reads
#   extra:
#	- can't change read-only variables
#	- error if var name bogus
#	- set -o allexport effects read
# ksh:
#	x check default variable: REPLY
#	- check -p, -s, -u options
#	- check var?prompt stuff
#	- "echo a b | read x y" sets x,y in parent shell (at&t)
# Regression: The first 39 of these tests are from the old Bugs script.
