Fixed the overshoot in the Bu::TafReader, it was reading the lookahead character

from the stream even when it should have known it was at the end, and then it
was reading an extra character after that anyway :-P  It is now fixed, and the
stream is positioned at the character immediately after the closing } of the
root taf group, great for things like the svtools.

+         * A processor for Libbu++ brand Mini Macros.  These are really simple, but
+         * still fairly flexible.  It's mainly text replacement, but with a few
+         * extras like filter functions and conditional text segments.  So far we
+         * don't support loops or anything, I'm not sure we ever will.
+         *
+         * Anatomy of a mini macro:
+         * - Every macro begins with a two character code, the first character is
+         *   always '{', the second character determines the operation to perform.
+         * - If the '{' is followed by a character that is not valid it is not
+         *   considered for expansion and the characters are copied to the output.
+         * - Every macro ends with a closing '}'
+         * - Macro types:
+         *   - '=': variable replacement.  The '=' is immediatley followed by the
+         *     name of the variable to replace, then any number of optional filter
+         *     segments.
+         *   - '?': conditional text.  The '?' is immediately followed by the
+         *     variable to test.  This works two ways, the variable can be alone, in
+         *     which case it's existance is tested, or it can be followed by a "="
+         *     and a string to compare to.  This is then followed by a text segment
+         *     that will be used if the test is true, and an optional text segment
+         *     to be used if the test is false.
+         * - Segments:
+         *   - Each segment is seperated by a colon.
+         *   - Filter segments give the name of the filter, followed by
+         *     parenthesies.  Parameters may be provided within the parenthesies.
+         *   - Text segments should always be quoted, but may contain any characters
+         *     within the quotes, backslash is used as per C/ANSI/ISO standard.
+         *     You can also quote any text using [" "] instead of quotes, which
+         *     allows for nested strings.  The [" token is only recognised within
+         *     a macro.
