         The quote stripping is not done correctly.

      Compared to what?  Do you have an example of history expansion that
      works "correctly"?

   Compared to the csh example that Rob mailed me.

Where is that example?  Here is /bin/csh, SunOs 4.0, Sun3:

    bfox@aurel$ /bin/csh
    bfox@aurel%ls foomar
    ls: foomar: No such file or directory
    bfox@aurel%echo "!ls"
    ls": Event not found.

   Csh stripped the quotes.

No it didn't.  And then, much to my confusion, you include an example of
tilde expansion, demonstrating that Csh does not expand tildes within
words: only where the tilde begins the word.  What relevance does this
have to my question about history expansion?

PS: I hacked history expansion do expand history references inside
matched quotes, using the close quote as a delimiter, since there is no
way to do that particular and useful expansion that I know of in Csh
history expansion.

That is to say:

	echo "!ls"

  expands to

	echo "ls foomar"

I don't know of a way to do this with Csh.
