missing @anchor mangling for docbook output

[Per Bothner]

When generating --docbook output, the name in an @anchor
does not get mangled, but the link does.

Using the latest texinfo from cvs:

$ cat test.texi
@setfilename test.info
@documentencoding UTF-8
@settitle A Test manual

@node Top, , (dir), (dir)
@top A Test manual

Allocating arrays (@pxref{Creating new Java arrays}) uses the same pattern.

@subsection Creating new Java arrays

@anchor{Creating new Java arrays}

$ /home/bothner/GNU/texinfo-cvs/+installed+/bin/texi2any --docbook 
test.texi

$ cat test.xml
<?xml version="1.0"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
