You folks are doing an oil & water mix-n-match of functions that does not 
mix well.

Since lha is capable of doing its own "shell expansion" when the -r is in 
effect, I have never used the extra leading : to invoke shell expansion.  

Besides that, the shells expansion is not all that useable as the 
expansion buffer is about 50k too small to hold all of a busy directory 
that has been extended several times.  I have, for that limited buffer 
reason, found shell expansion to be less than useful, and capable of 
crashing the shell to boot as it did not appear to handle a buffer 
overflow at all well.

So don't use the shell expension, just let lha do its own 1 at a time 
thing.  I haven't run it in a while, but I think to do a full directory 
into one archive file, that you should cd back out one level and as shown 
in the help, name the directory you want in the archive as something like 
'Oct89/', note slash & no quotes, and put the -w work file right there in 
the parent directory.  Or wherever you are organized to want it as it can 
take a full pathlist of a reasonable length IIRC.

I suppose its possible you could work IN the directory you want, by 
specifying a ./ as the src, but then you would have to put the -w file as 
../filename.lha (out of that directry IOW) else you would be recursively 
backing up the file you are creating.  ISTR doing that once a couple 
decades back up the log and made a mess to clean up when the disk or the 
FD.SEG was full.
