[bug#60609] [PATCH] gnu: git-annex: Patch 'git-annex webapp' to use hardcoded xdg-open.

Hi all,

I was using git-annex for the very first time today and when I tried
to run 'git-annex webapp' I got this error:

    Launching web browser on file:///tmp/webapp3975-0.html
    git-annex: xdg-open: createProcess: posix_spawnp: does not exist
(No such file or directory)
    WebApp crashed: xdg-open: createProcess: posix_spawnp: does not
exist (No such file or directory)

I think this should just work so I wrote a patch to replace a couple
of loose references to xdg-open with a hardcoded store path.

How does it look?

Thanks,

- Dave
