minor iconvlist() bug in r-devel

That file is created by

$(top_builddir)/library/$(pkg)/iconvlist: most
         @iconv -l > $@ 2> /dev/null || touch $@

What version of iconv -l is that produces such a list?  That in glibc
2.3.4 does not produce the header when redirected.

Your fix is not safe: iconv in libiconv produces items separated by
space or newline.  Looks like we will have to work harder to
distinguish the two.

This is on r-devel from 2005-03-15. iconvlist() uses (at least some
of the time)

icfile <- system.file("iconvlist", package = "utils")

which looks like

"""
The following list contain all the coded character sets known. 
This does not necessarily mean that all combinations of these names
can be used for the FROM and TO command line parameters.  One coded
character set can be listed with several different names (aliases).

 437//
500//

which leads to

tail(iconvlist(), n = 40)

[1] "WS2"          "YU"           "all"          "all"         
"and" [6] "be"           "be"           "can"          "can"

"combinations" "command" [16] "contain"      "different"    "does"

"the"          "these"        "used"         "with"

A possible fix seems to be to replace

   ext <- readLines(icfile)

by

   ext <- grep("/$", readLines(icfile), value = TRUE)

but I don't know if that's guaranteed to work.
