Can you please change my email address on the pretest list from
f.j.wright@qmul.ac.uk to f.j.wright@live.co.uk? (I don't think I can do this
myself, can I?) Thanks.

About 10 years ago, I wrote a replacement for `wildcard-to-regexp' (defined
in files.el) that supports bash-style {a,b,...} expansion controlled by the
customizable option `wildcard-to-regexp-expand-{}'. I have just updated this
for Emacs 24 at the request of a user who said he has found it useful. (I
had forgotten that I ever released it, but I must have done!) I attach my
current version.

Would you like to include this modification in a future version of Emacs or
as a package? If the former then I'll provide it as a file of diffs to
files.el. If the latter then I'll provide it in the rigtht format for a
package. (If neither then I'll think about releasing it somewhere else, such
as EmacsWiki.) I have already assigned to the FSF copyright of any Emacs
modifications that I might make.

Best wishes, Francis
