Hmph. So the fix would be something like this?
repo_info="$(git rev-parse --git-dir --is-inside-git-dir \
--is-bare-repository --is-inside-work-tree \
- --short HEAD 2>/dev/null)"
+ --short HEAD 2>/dev/null || :)"
I am too afraid to ask what a user would try to achieve by doing the
"set -e" thing in an interactive session. It is understandable (I
am not saying I think it is necessarily a good idea) to do so in a
script, but for an interactive shell?
