I think the right thing to do is to leave the default prompts
alone, and teach people how to set up prompts. There is no way you
can cater to all tastes and all shells, people invariably change
them, and anyway, we should make it easy for people to change
prompts.
The defaults are functional, though not pretty. No one can
agree on what is pretty. I think users should be allowed to make
their own choices.
I append my personal prompt setting scheme, in hopes this
inspires someone else (any improvements greatly appreciated)

##
## prunepwd.pl - Prune a `pwd` string
##
## prunepwd prunes the current working directory path to a size that
## is reasonable for a prompt. The size limit is specified by
## optional command line argument. The default is 25.
##
## If the path is a descendent of the home directory path, the leading
## home directory path is replaced with ``~''. Otherwise, a leading
## //node_name (ala Apollo) is replaced with ``node_name:''.
## Directories are trimmed from the beginning of the path (following
## the node name) until the path length (including node name) is less
## than the limit. The last directory in the path is never pruned,
## even if its length exceeds the limit. The set of pruned
## directories is replaced by ``...''.
##
## Examples:
##
## //srivasta/usr/abc/def/ghi/jkl/mno/pqr/stu/vwx (before)
## srivasta:/.../pqr/stu/vwx (after)
##
## //srivasta/user/mse/learn/perl/chapter1 (before)
## ~/learn/perl/chapter1 (after)
##

} else {
## Unix style path (/path/...)
$node = "";
}
}
$len = length ($node) + length ($cwd);
if ($len > $pwdsz) {
@path = split (/\//, $cwd);
##
## always leave the final component of the path even if its
## length is greater than the limit.
##
if ($#path > 1) {
##
## Find number of leading components in path to skip
##
for ($skip = 0; $len > $pwdsz && $skip < ($#path); $skip++) {

I think an embryo/fetus/baby becomes a "person" when it is smarter
than a non-primate like a dog. By those standards, chimpanzees and
gorillas are persons (although somewhat cognitively impaired -- kind
of like Fundamentalist Christians), but human newborns are not. Dave
