bug#8492: 23.3; Time to use a different binding for completion?

[Reuben Thomas]

Emacs binds various completion functions to M-Tab, which is already used
by many window managers, including Compiz and Metacity, i.e. the WMs one
is likely to use on a modern GNU system, for switching between open
windows.

Is it therefore time to admit defeat and find an alternative binding for
completion functions, even if it’s an extra binding rather than simply a
different one?

XHTML validation header that sets the DTD to XHTML.  This will
not be inserted in the buffer but completion and XHTML validation
will assume it is there so both error checking and completion
will work.

Do you want to add a fictive XHTML validation header? (y or n)
