Do `query-replace-regexp' of FROM with TO on all files listed in tags table.
Third arg DELIMITED (prefix arg) means replace only word-delimited matches.
If you exit (C-g, RET or q), you can resume the query replace
with the command M-,.
Fourth arg FILE-LIST-FORM non-nil means initialize the replacement loop.
Fifth and sixth arguments START and END are accepted, for compatibility
with `query-replace-regexp', and ignored.
If FILE-LIST-FORM is non-nil, it is a form to evaluate to
produce the list of files to search.
See also the documentation of the variable `tags-file-name'.
