Ahhh, symlink!
get_repo_base does this:
get_repo_base() {
(cd "$1" && (cd .git ; pwd)) 2> /dev/null
}
and is used like this:
# Turn the source into an absolute path if
# it is local
if base=$(get_repo_base "$repo"); then
repo="$base"
local=yes
fi
That is, get_repo_base does:
* first try to cd to ../torvalds/linux-2.6.git; if it fails
then give up.
* then further cd down to .git if we can but do not worry about
it if we can't. Report where we are and succeed.
If the above "fails", the caller considers the cloned-from
repository a non-local one, and turns off -l -s optimization.
The above sequence is called before we create the new directory
and chdir to it. Maybe pwd has funny behaviour (e.g. $PWD) and
we need to explicitly say /bin/pwd or somesuch...
