How lame! It's a '!' in a quoted string. Another example
of posix braindeath -- how long before people realize that the
thing branded 'posix' now isn't the real posix that was started
to *describe* behaviors, not prescribe or proscribe behaviors.
Do you realize that this prompt expansion was in ksh since at least
ksh-86? ksh-88 was one of the Posix base documents, and that
expansion was estabished behavior by the time Posix started its work.

Haven't used ksh for some time....I thought the '!' stuff came
from csh? It seemed so pointless, since having to look up
things by command number I thought, was way too much work... searching
via a string in the line seemed so much faster...
For stuff I typed last week or earlier, I'd use grep on the hist files.
I thought to have all my hist files merged and deduped... but the resulting
master hist file -- .. I used it for a while (somewhat accidently as it was
renamed to a normal hist file @ around 2-3M in length).
command response was quite slow (took a while to figure out it was
the history updating every command that caused a delay of about
2-3 seconds/command).
I don't think I have all the kinks in the combining routines worked
out yet either... but certainly wouldn't want to switch to the newest
master @ 6.4M until history updating is sped up a bit... (I'm not
holding my break... at least I can still browse/grep it by tty#)...
