Summary	0002839: some files are opened read-write that should be opened read-only
Description	I have a complicated multi-user setup of DF involving unionfs and a snazzy client+server. After anyone plays for a while, I notice that their per-user directory ends up polluted with (apparently unmodified) data/index, data/announcement/, data/dipscript/, and data/help/* files. These are harmless until I upgrade DF, after which they are stale and can cause problems; data/index is the big one, but files in data/announcement/* caused all combat announcements to totally disappear in the 31.10 - 31.11 transition. Manually cleaning out extra files fixes it, but is tedious. (The per-user directories are supposed to contain only data/save/, possibly data/init/, and possibly modified raws.) This is caused when the files are opened read-write; though no modifications appear to be made, unionfs copy-on-write is triggered when the file is opened, for performance reasons.
Steps To Reproduce	data/help/* and data/dipscript/* files are ALWAYS opened read-write. This can be observed by wandering the help system briefly.
Additional Information	This is probably an easy fix, and the result is sometimes explosive, though the necessary conditions for problems are incredibly rare. I may be the only user out there who will ever be affected by this. There needs to be a priority below "low."
