Regarding the following paragraph that appears in the glibc manual,
section 6.5.4.2 Finding the conversion path in `iconv`
(http://www.gnu.org/software/libc/manual/html_node/glibc-iconv-Implementation.html):

Is it currently possible to use regular expressions in the "from" and/or "to"
columns of `module` lines? If not, what was the last discussion on this
feature?
