I see. I came to this example from a real-world problem and, in case
someone can help, here it is. I'd like to append a path to CPATH
(separating it from the current contents of CPATH with a colon only if CPATH
is set and is not empty). The path-to-append points under usr1's home
directory. Also this should work in contexts such as CPATH=... <some
command>. I tried CPATH="${CPATH}${CPATH:+:}"~usr1/blah/blah. (I quote
expansions just to be on the safe side, though I think home directories may
not contain spaces.) Of course, this did not work for the reason pointed
above. However, removing the quotes still does not make the
tilde-expression to expand. How can I achieve my goal?
