docs(session-logs): scope nullglob and use while-read in helper

injinj · injinj · commit 2edb418b0de3 · 2026-05-29T02:34:26.000-07:00
Address Greptile review feedback on PR #71537: * nullglob is now saved and restored inside list_session_transcripts so the helper does not change the caller shell environment when sourced. * Replace 'for f in $(list_session_transcripts)' tip with a 'while IFS= read -r' loop so paths with spaces or other IFS characters are handled correctly. Include a worked example using the same date+size listing the surrounding section already documents. Doc only, no runtime behavior change.
