Agreed!  I *know* I've had conflicts in CVSROOT/cvswrappers in
the past (having a text file treated as binary because it happens
to have an extension that also signifies some binary format);
just can't remember what they were.

But here are some counterexamples anyway:

  - .doc:  we all know what M$ thinks it means, but other people
    have their own ideas.  I've seen text files with .doc
    extensions, and I'd bet other word- or document-processors
    have used it too

  - .cfg:  some kind of configuration file ... but it could be
    anything from Windows-ini format to XML to pseudo-Lisp to

  - .cgi:  again, that says how it functions -- in this case,
    what its API is -- but says *nothing* about the file format;
    CGI "scripts" can be in any language you like, including C

  - In general, on *NIX machines where extensions are more a
    convention than an OS-mandated thing, people tend to play
    fast and loose with them.  E.g. one could conceive of a
    directory full of files named for Internet domains --
    including Australian ones ending in ".au", which is also an
    audio format

  - And the killer is .bak:  can be anything under the sun, of
    course.  Usually people don't check them in, but it would be
    foolish in the extreme to presume they *never* do, and to
    make doing so functionally useless

That's just from the A-D part of a list of file extensions.  I'm
sure there are lots more conflicts in E-Z.

Oh, and of course there's .sys;  even M$ can't decide what that
