Clean up script gdb/contrib/expect-read1.sh by: - fixing shellcheck warnings, - using mktemp (which takes TMPDIR into account) instead of a hardcoded "/tmp/expect-read1.$$.so", - adding comments, and - adding emacs / vi settings for local tab size 2 (copied from ./ltmain.sh). Tested on x86_64-linux. Approved-by: Kevin Buettner <kevinb@redhat.com>
