=== *Description* ============================================================
alias r="fc -e -" is my standard ksh-ism forever; I see there's a better name
for
the command, "hist", now, but both suffer from the same problem: the shell
complains about the number of arguments given; the alias is irrelevant.
that is:
fc -e - vi
fc -s vi
both fail with
ksh93: fc: -e - requires single argument
hist -e - vi
hist -s vi
fail with
ksh93: hist: -e - requires single argument

Seeing that April and Glenn Fowler of AT&T both can't reproduce, I started
thinking about my environment, and discovered I have an alias for 'hist'
defined that is
apparently the source of the problem:
alias hist="fc -l -100000"
it doesn't affect the existing /bin/ksh, but it breaks ksh93; I assume because
1) fc is internally translated to 'hist', and then
2) hist is alias-expanded as above
...or something, because if I actually enter "fc -l -1000000 -e - vi", it
doesn't
do what I expect, but it doesn't give the error message above either....
anyway, the extra alias is unnecessary with ksh93, and seems to be the source
of the problem.
