`pcomplete-suffix-list' is an obsolete variable (as of 24.1) about helm HOT 6 CLOSED

these variables are used internally by pcomplete and are needed.
`pcomplete-suffix-list' is needed on emacs-23, so we keep it for compatibility.

Okay so they are used by pcomplete internally.

But why do we need a dynamic value for them? Especially since they are initialized to be eq to the global values and then never changed.

@tarsius The code implies they could be changed under some circumstance and the original value needs to be saved. Do you know for sure they will never be changed?

from helm.

No, but who do you expect to change them?

If the values are potentially changed by some code called by helm-esh-get-candidates then I agree. (Edit: I assume this is the case just want to make sure.)

If some code that is part of pcomplete changes it then this is either a feature or a bug of pcomplete.

Finally if the local bindings are there to protect against changes made to these variables elsewhere (not by pcomplete internal code and not from within helm-esh-get-candidates) then this obviously does not work.

You have to wrap all `pcomplete-completions' calls with these
initialized values.
Expect bugs if you don't.

and then never changed.
They are changed internally by pcomplete during the process.
However, it behave differently between emacs23 and 24.
The code have been heavily modified in emacs24.
So indeed some value are never changed in your emacs version but maybe
used and changed by pcomplete in other emacs versions.

Okay fair enough.
