Change regular-expression primitives to treat failure-stack overflow
as equivalent to "no match". Also, increase the maximum size of the
failure stack from 1000 to 20000. This is important because it is far
too easy to overflow the stack, the stack-overflow errors cause Edwin
to bomb out. This is a problem because stack-overflow errors can be
caused by user data -- the proximate example being a News message that
bombed out the News reader because it had a header line was too
complicated to match. Better to fail in these situations than to
error.

Fix bug: scheme_to_interface must clear the floating-point register
stack. Otherwise, inexplicable floating-point errors can occur. An
example of such an error can be created by typing `-1e-194' at a
freshly-booted scheme.
The actual problem is somewhat involved. The C compiler assumes that
all of the floating-point registers are empty on the entry to any
procedure. As a consequence of this assumption, it feels free to use
all 8 of the registers. However, if this assumption is violated, a C
procedure that uses too many registers will signal a floating-point
stack overflow.
However, the Scheme compiler does not follow this convention; more
precisely, since it was originally designed to use reasonable
floating-point hardware, in which the floating-point registers are
organized as a bank of registers rather than a stack, it doesn't do
anything about popping registers when it is done with them. As a
consequence, floating-point operations generated by the Scheme
compiler often leave values on the floating-point stack.
To work around this without redesigning the compiler, the
compiled-code interface clears out the stack whenever it transfers
between C and Scheme code. The bug fixed by this revision was a
transfer point that did not have code to clear out the stack.

Implement VHDL mode. Generalize the keyword parser used by Verilog
mode so that it is powerful enough to parse both languages. Implement
a high-level extensible pattern matcher to allow the VHDL indenter to
recognize keyword contexts in cases where it is necessary.

Create new data type for a compiled regular expression; this type
contains the case-fold information used to compile the regexp. Modify
the low-level regular-expression procedures to accept this new type
and to no longer have an argument for case-fold. Modify the
high-level regular-expression procedures to accept a compiled regular
expression in place of a regular-expression string; in this case the
optional case-fold argument is ignored.
Edit all references to the low-level procedures to conform to this new
design.

Change to conform to new design of Edwin regular-expression

Change data structures and calling conventions of screen abstraction
so that "highlighting" can specify the "face" in which the text will
appear. This generalization allows us to modify the terminal
abstractions to support multiple fonts and colors.
