Still more examples of filenames to avoid:

core             may be prone to abrupt disappearance \
*.core           "                                    | from glancing at
a.out            "                                    | /etc/daily
*.o              "                                    |
*.CKP            "                                    |
.emacs_[0-9]*    "                                    |
#*               " (mh)                               |
,*               " (mh)                               |
.#*              "                                    /
TRAILER!!!       can make some cpio implementations exit prematurely

I wonder if anybody's ever tried to draw up a cross-platform anywhere-near-
complete list....
