Yes, and the csh completion syntax is challenging for complex commands. 
An external program can be run to provide completions, and that's 
probably the way to go for the really complex ones.  I've avoided that 
so far, but complex commands with subcommands like git, pkg, zfs, and 
svn might be easier, clearer, or more maintainable to do that way.

Completions are not really the same kind of problem, or at least they 
don't differ because people use the same programs.  I think of them as a 
sort of built-in help for input, helping to make legitimate choices 
rather than what I might remember.  And I would like to see a much 
larger default set of autocompletions.  They make so many commands 
easier to use.

Sure, my list is a collection anyway.  Many were collected from csh/tcsh 
examples and online sources, some I wrote by myself, and some were 
collaborations.  The original "make" completion that showed all 
available targets was created with help from forum members.  Then 
make(1) changed, and the new one made it much simpler.  Incidentally, 
the completion for "make -V ", which should complete with all available 
make variables, does not yet work.

The sharp-eyed will see a completion for kldreload, which does not 
exist in the wild but is an alias:

   alias kldreload 'kldunload \!* && sleep 0.1 && kldload \!*'

(Used mostly for reloading the VirtualBox kernel module after a 
rebuild.)

Some of these are integrated into /usr/share/examples/csh/dot.cshrc. 
There are more completions in /usr/share/examples/tcsh/complete.tcsh, 
too.
