Subject: "stg series" on an un-inited branch gives weird error
X-Git-Tag: v0.14.3~659
X-Git-Url: https://git.distorted.org.uk/~mdw/stgit/commitdiff_plain/40e65b928d0429090a39843c1a81dec31f4d38e2?hp=7c09df84663028d46af9d79d0cbb37532f94deb8

"stg series" on an un-inited branch gives weird error

If I try an "stg series" command on a repository that hasn't yet been
initialized, I get a non-intuitive error message:

stg series: [Errno 2] No such file or directory:
'/home/cel/src/git/main/.git/patches/master/applied'

This patch replaces the message with a reasonable explanation.
