RCS ids in sources, argh

[Stan Shebs]

I know some people are absurdly fond of RCS Id: strings in source
code, but they are a mondo pain for anybody who imports FSF sources
into their own repository - every one of them looks like a conflict
to CVS, and has to be fixed via manual edits.  This is pretty tedious
when it happens to half the files in docs/html for instance.  Could
we *please* not have id strings in the sources?
