[ 1179660 ] limits of bfloat()

o In RATION1, add a check for a possible division by zero. This fixes
the immediate bug, but we should consider a different algorithm.
o Add a few comments too.

Change ":if-exists :overwrite" to ":if-exists :supersede" in TEST-BATCH.
This makes batch ("tests/rtestfoo.mac", 'test) succeed, whereas without
the change, it fails with "rtestfoo.ERR does not exist".
Error appears in both clisp and gcl versions of current cvs Maxima,
both are fixed by the change.

rtest13.mac:
o Remove the (commented) tests about matchfix and friends because
they're actually tested in rtest13s.mac.

rtest13s.mac:
o Don't verbify the expected results because matchfix and friends
return strings now.
o Added a few more tests for case-sensitivity of operators.

Fix for bugs:

[ 797401 ] infix should return string, not internal op

o Return the (first) operator string instead of the internal op.
o Apply to all operators such as prefix, postfix, nary, matchfix,
nofix.

[ 1173788 ] assigning operators - case sensitivity problem
o Don't upcase the operator for prefix, postfix, nary, matchfix,
nofix, and infix.

Other fixes:
o The error message for incorrect syntax printed the operator with the
wrong case.
o Some nicer indentation in a couple of functions.

Modify $printfile to detect eof more carefully.
With this change, printfile ("foo.mac") succeeds without error on clisp and cmucl.
Without it, prints content of file, then prints error message "End-of-File on #<Stream>"
(cmucl, similar for clisp). The error message doesn't appear in gcl, but gcl Maxima
is happy with the modified $printfile.

Join pieces of "%%CreatedDate" string which was broken across three
lines for some reason. With this change, "plot2d_ps (sin(x), [x, -%pi, %pi])"
succeeds, fails without it. (PS viewer complained about malformed PS file.)

- Regularize case of proper name of package to itensor (change instances
of ITENSOR and Itensor to itensor)
- Regularize case of some other words (MAXIMA -> Maxima, begin titles
with initial capital followed by all lowercase, etc)
- Strike out commented-out @node and @unnumberedsec tags
- Change variable name exp to expr throughout
- Enclose names of arguments in @var (changed some @code to @var for this)
- Added @defunx to some functions which take variable numbers of arguments
- Separate items in list of args in @defun by 1 space
- Write expr_1, tensor_1, etc instead of expr1, tensor1, etc
- Refer to functions by names alone throughout (struck out some () for this)
- Change some lowercase l to uppercase L (l easily confused with 1)
- Strike out "[itensor package]" at beginning of some items
(not used consistently, and not used in descriptions of other packages)
- Left some notes for further work

Enclose names in @var or @code as appropriate, change some wording,
throw in comments for future reference.
