There is a bug that `helm-projectile-find-file' is interrupted by an

unexpected input event. After inspecting emacs code, I found it can

simply reproduce by follow code, and the expected out is a path,

while actually result is t:

emacs --batch --eval "(message \"%s\" (catch 'input

(let ((throw-on-input 'input)) (expand-file-name \"a.iso/b\" \"/\"))))"

And a backtrace can be generated by removing the `(catch input', it's

attached as "backtrace-unexpected-input-event-for-expand-file-name".

From the backtrace, it seems caused by ` tramp-archive-file-name-handler’.

How to avoid input event in this situation? Thanks
