Please do this as git rm and commit.

I had a look at this, bootstrap is supposed to add a dummy ChangeLog for 
this, but does not, depending upon what bs_echo got set to.

func_ifcontains has this:
    # The embedded echo is to squash whitespace before globbing.
    _G_wslist=`$bs_echo " "$1" "`
    _G_member=$2
    _G_yes_cmd=$3
    _G_no_cmd=${4-":"}

    case $_G_wslist in
      *" $_G_member "*)

and is called like this:
func_ifcontains '
        announce-gen
        do-release-commit-and-tag
        gendocs
        git-version-gen
        gitlog-to-changelog
        gnu-web-doc-update
        gnupload
        maintainer-makefile
        readme-release
' gitlog-to-changelog func_ensure_changelog

If bs_echo is printf '%s\n' then the embedded newlines in $_G_wslist do 
not get eliminated by the `$bs_echo " "$1" "` and " gitlog-to-changelog 
" (with those spaces on both sides) is not in the string, so no 
ChangeLog is created.

This function doesn't appear to be part of gnulib yet, and I'm not sure 
how best to fix it.

Changing $bs_echo to 'echo' should work, so should using set foo $1; 
shift (after assigning $2,3 and 4) and then assigning _G_wslist=" $@ ".

I'll look to see how we eliminate spaces and newlines elsewhere in 
libtool and use the same idiom.

Peter
