Hi Emacs devs,

I am using GNU Emacs 24.1.50.1 (built 2012-07-21). I see the file naming
scheme for lock files is `.#<old name>'. I seemed to recall there was
trailing hash like this `.#<old name>#'. But on the Emacs help list I
was told there was no trailing hash in the past. So my request is, can a
trailing hash be added?

My issue in particular is, the lock file gets picked by a glob like
`*.cxx'; with a trailing hash, this would only match source files. This
can be a problem with tools that only support very basic globbing.

Thanks for your consideration.

PS: I'm not subscribed, please CC me in any discussion on this topic.

I don't think Emacs needs to change the (very long-standing) name of
lockfiles for the sake of inflexible tools that cannot exclude dotfiles
(note that normal shell globbing does not match dotfiles at all). Emacs
24.2 will have an option `create-lockfiles' that you can set to nil to
disable the generation of lockfiles altogether, hopefully that works for
you.

I guess you are right. I use the tool only because I have to, it's a
real pain. :(

This will work well thank you. :)
