(Rx Regexps): Remove this section, Rx

is not in the core and we don't want to confuse anyone with it and the
builtin posix regexps.

-@section The Rx Regular Expression Library
-
-[FIXME: this is taken from Gary and Mark's quick summaries and should be
-reviewed and expanded.  Rx is pretty stable, so could already be done!]
-
-@cindex rx
-@cindex finite automaton
-
-The @file{guile-lang-allover} package provides an interface to Tom
-Lord's Rx library (currently only to POSIX regular expressions).  Use of
-the library requires a two step process: compile a regular expression
-into an efficient structure, then use the structure in any number of
-string comparisons.
-
-For example, given the regular expression @samp{abc.} (which matches any
-string containing @samp{abc} followed by any single character):
-
-@smalllisp
-guile> @kbd{(define r (regcomp "abc."))}
-guile> @kbd{r}
-#<rgx abc.>
-guile> @kbd{(regexec r "abc")}
-#f
-guile> @kbd{(regexec r "abcd")}
-#((0 . 4))
-guile>
-@end smalllisp
-
-The definitions of @code{regcomp} and @code{regexec} are as follows:
-
-@deffn {Scheme Procedure} regcomp pattern [flags]
-Compile the regular expression pattern using POSIX rules.  Flags is
-optional and should be specified using symbolic names:
-@defvar REG_EXTENDED
-use extended POSIX syntax
-@end defvar
-@defvar REG_ICASE
-use case-insensitive matching
-@end defvar
-@defvar REG_NEWLINE
-allow anchors to match after newline characters in the
-string and prevents @code{.} or @code{[^...]} from matching newlines.
-@end defvar
-
-The @code{logior} procedure can be used to combine multiple flags.
-The default is to use
-POSIX basic syntax, which makes @code{+} and @code{?}  literals and @code{\+}
-and @code{\?}
-operators.  Backslashes in @var{pattern} must be escaped if specified in a
-literal string e.g., @code{"\\(a\\)\\?"}.
-@end deffn
-
-@deffn {Scheme Procedure} regexec regex string [match-pick] [flags]
-Match @var{string} against the compiled POSIX regular expression
-@var{regex}.
-@var{match-pick} and @var{flags} are optional.  Possible flags (which can be
-combined using the logior procedure) are:
-
-@defvar REG_NOTBOL
-The beginning of line operator won't match the beginning of
-@var{string} (presumably because it's not the beginning of a line)
-@end defvar
-
-@defvar REG_NOTEOL
-Similar to REG_NOTBOL, but prevents the end of line operator
-from matching the end of @var{string}.
-@end defvar
-
-If no match is possible, regexec returns #f.  Otherwise @var{match-pick}
-determines the return value:
-
-@code{#t} or unspecified: a newly-allocated vector is returned,
-containing pairs with the indices of the matched part of @var{string} and any
-substrings.
-
-@code{""}: a list is returned: the first element contains a nested list
-with the matched part of @var{string} surrounded by the the unmatched parts.
-Remaining elements are matched substrings (if any).  All returned
-substrings share memory with @var{string}.
-
-@code{#f}: regexec returns #t if a match is made, otherwise #f.
-
-vector: the supplied vector is returned, with the first element replaced
-by a pair containing the indices of the matched portion of @var{string} and
-further elements replaced by pairs containing the indices of matched
-substrings (if any).
-
-list: a list will be returned, with each member of the list
-specified by a code in the corresponding position of the supplied list:
-
-a number: the numbered matching substring (0 for the entire match).
-
-@code{#\<}: the beginning of @var{string} to the beginning of the part matched
-by regex.
-
-@code{#\>}: the end of the matched part of @var{string} to the end of
-@var{string}.
-
-@code{#\c}: the "final tag", which seems to be associated with the "cut
-operator", which doesn't seem to be available through the posix
-interface.
-
-e.g., @code{(list #\< 0 1 #\>)}.  The returned substrings share memory with
-@var{string}.
-@end deffn
-
-Here are some other procedures that might be used when using regular
-expressions:
-
-@deffn {Scheme Procedure} compiled-regexp? obj
-Test whether obj is a compiled regular expression.
-@end deffn
-
-@deffn {Scheme Procedure} regexp->dfa regex [flags]
