Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

The completion functionality in etags.el (emacs/21.3/lisp/progmodes/)
only works with one tags table at a time. To trigger bug, load two
different tags tables with visit-tags-table. M-. TAB TAB will only
show completions for one of the two tables. A workaround is to create
a TAGS file with "etags -i" which includes all of the other TAGS files
that the user wants to search.
