This mostly-exhaustive test ensures that the illegal-character error
implemented in the previous commit is actually generated for most every
illegal character.

+/* After subtracting out the legal characters (see test
+ * 140-legal-characters.c), any other possible character must be
+ * illegal. That leaves:
+ *
+ * Illegal in all contexts:
+ *
+ * 0x00 - 0x08 (^@ - ^H)
+ * 0x0E - 0x1F (^N - ^Z, ^[, ^\, ^], ^^, ^_)
+ * 0x22 (")
+ * 0x24 ($)
+ * 0x27 (')
+ * 0x40 (@)
+ * 0x60 (`)
+ * 0x7F (DEL or ^?)
+ * 0x80 - 0xFF (non-ASCII)
+ *
+ * Illegal in some contexts:
+ *
+ * 0x23 (#), not introducting a directive, not as part of past operator
+ * 0x5C (\), not as last character of a line
+ *
+ * This file tests at least one occurence of most of the above
+ * characters. The exceptions are:
+ *
+ * 0x00: This character would be tricky to test. The calling
+ * convention of bison to the lexer is such that a return value
+ * of 0 indicates end-of-file. So without any direct support
+ * for the 0x00 character, it is being interpreted as
+ * end-of-file. This semms legitimate enough, (since the 0x00
+ * character is illegal).
+ *
+ * 0x80 -0xFF: Only 25% of these characters are represented here.
