address@hidden process-file-side-effects
+This variable indicates, whether a call of @code{process-file} changes
+remote files.
+
+Per default, this variable is always set to @code{t}, meaning that a
+call of @code{process-file} could potentially change any file on a

+shall be set only by let-binding.
