[Rd] minor iconvlist() bug in r-devel

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).


which leads to 

> tail(iconvlist(), n = 40)
 [1] "WS2"          "YU"           "all"          "all"          "and"
 [6] "be"           "be"           "can"          "can"      "character"
[11] "character"    "coded"        "coded"     "combinations" "command"
[16] "contain"      "different"    "does"         "following"    "for"
[21] "known."       "line"         "list"         "listed"       "mean"
[26] "names"        "names"        "necessarily"  "not"          "of"
[31] "parameters."  "set"          "sets"         "several"      "that"
[36] "the"          "the"          "these"        "used"         "with"

A possible fix seems to be to replace

    ext <- readLines(icfile)


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

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