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).

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)
by
ext <- grep("/$", readLines(icfile), value = TRUE)
but I don't know if that's guaranteed to work.
