Test that the shipped autostart parses to what it documents

The template is mostly prose, and `#` starts a comment wherever a word would
start -- so a comment marker landing in the wrong column drops a command
silently rather than failing. Parsing the real file in a test means editing
the explanatory text around a command cannot quietly disable it.

Tests only; no behaviour change, so the installed session binary is unaffected.
