empty double backquotes unpredictable?

[Ron Kuris]

When running the csh, I typed only two backquotes (``) and got:
/s2/acct/rk/bin/: cannot execute

My path was:
/usr/bin:/bin:/usr/ucb:/s2/acct/rk/bin:/s/rk/rel/bin

When I removed /s2/acct/rk/bin from my path, the error changes to:
: cannot execute

What gives?  I tried nifty things like: ``file
which runs /s2/acct/rk/bin/file.  Then I tried: echo ``
and got nothing.  Seems real bizzare.  Any explanations?

Send E-mail and I'll summarize.
