ERC file names clash in 8+3 filesystems

[Eli Zaretskii]

Some of the files in the ERC package installed in the Emacs CVS tree
have names that are not unique in the first 8+3 characters.  DOSCHK
found the following clashes:

    The following resolve to the same DOS file names:
    CHANGELO.200   : ./lisp/erc/ChangeLog.2001
                     ./lisp/erc/ChangeLog.2002
                     ./lisp/erc/ChangeLog.2003
                     ./lisp/erc/ChangeLog.2004
                     ./lisp/erc/ChangeLog.2005
    ERC-AUTO.EL    : ./lisp/erc/erc-autoaway.el
                     ./lisp/erc/erc-autojoin.el
    ERC-COMP.EL    : ./lisp/erc/erc-compat.el
                     ./lisp/erc/erc-complete.el
    ERC-NETS.EL    : ./lisp/erc/erc-nets.el
                     ./lisp/erc/erc-netsplit.el
    ERC-NICK.EL    : ./lisp/erc/erc-nicklist.el
                     ./lisp/erc/erc-nickserv.el

This makes unpacking the Emacs tarball on 8+3 filesystems a pain.  Can
the offending files be renamed somehow?  (For ChangeLog.* files I'd
suggest ChangeLog.01, ChangeLog.02 etc.)
