If the completion-at-point system is triggered, but there is no REPL buffer, the julia-snail-repl-completion-at-point function still attempts to communicate with the REPL buffer, yielding the following message:
completion--some: No Julia REPL buffer *julia* found; run
julia-snail
Unfortunately, no other completion-at-point-functions are allowed to attempt completion, so no completion is performed, even if later entries in completion-at-point-functions could have handled it (e.g., the ones provided by julia-mode).
The documentation for completion-at-point-functions says to return nil if the completion function is not applicable. This commit changes julia-snail-repl-completion-at-point to check that the REPL buffer exists, and if it doesn't, it returns nil, allowing other completion-at-point-functions to take a turn.
