Print/read error with make-pathname

[Raymond Toy]

(make-pathname :directory '(:absolute "tmp" "" "a" "" "b")) -> #P"/tmp//a/b/". But #P"/tmp//a/b/"}} does not read back to the equivalent pathname. The multiple slashes are smashed into one so the result is the same as {{{#P/tmp/a/b/".

CMUCL should print the pathname as #P(:directory (:absolute "tmp" "" "a" "" "b")).

Fix ticket:50

Check if "" (and "/") is in the list of directories and signal an error so that we use the #P(...) syntax to print out the pathname readably.

Update the pot and po files accordingly.

Fix ticket:50

Catch the case of " " and signal an error so that we can print such pathnames using the #P(...) syntax. Also catch the case where the directory includes an explicit directory separator, "/", which would not be printed readably either.

Update the pot file too.
