and some sections have moved around).
(2) Make pointers from maxima.texi to grobner.texi.
(3) Put grobner.texi on list of files in

Make Maxima comfortable with partially-evaluated Boolean expressions
by merging code from share/contrib/boolsimp.lisp into src.
(Only the stuff for Boolean expressions has been brought over;
the stuff for partially-evaluated conditional expressions was not.)

The global flag prederror is still honored. When prederror=true,
Boolean expressions which evaluate (under "is", "if",
or one of the operators "and", "or", or "not") to something
other than true or false trigger an error.
The default value of prederror is now false (was true).

With these modifications, run_testsuite() (including new tests for
Boolean expressions) succeeds without unexpected errors.

Residual strangeness: "and", "or", and "not" cause evaluation of
their operands via MEVALP. So (foo or bar) is equivalent to
(?mevalp(foo) or ?mevalp(bar)). This is mostly OK but for operands
which are a=b or a#b, MEVALP always returns T or NIL so "and", "or",
and "not" turn anything with = or # into true or false. I'm inclined
to think that's a bug. (The structure of the previous code was
pretty much entirely preserved, which is the source of this bug;
there may be other strangeness present for the same reason.)

* doc/info/Operators.texi:
Update descriptions of "and", "or", and "not"
Update descriptions of "equal" and "notequal"

* doc/info/Program.texi:
Update description of "if"

* share/contrib/boolsimp/boolsimp.lisp:
Cut out code which was merged into various src files

* share/contrib/boolsimp/rtest_boolsimp.mac:
Cut out tests which were moved to tests/rtest_boolean.mac

* src/acall.lisp:
Cut $MAYBE (redefined elsewhere)
Cut special declaration for PATEVALLED

* src/asum.lisp:
Modify NARY1 to better flatten Boolean expressions

* src/compar.lisp:
Change default value of $PREDERROR to NIL
Cut out obsolete special PATEVALLED (now a lexical variable)
Paste in lengthy comments about evaluation and simplification
policies for Boolean expressions
Redefine $MAYBE

Redefine MAND, MOR, and MNOT

* src/trpred.lisp:
Cut out translation properties for MAND, MOR, and MNOT

* tests/
Put rtest_boolean.mac on list of files
Put rtest_mset.mac on list (was omitted by mistake before)

* tests/rtest_boolean.mac: (new)
