Issues with the new release #1318

Did brew upgrade yesterday and ran into at least two issues which make it a bit hard to use.

Issue 1: sl pull exits 255

Potential root cause: The post-pull prmarker hook (sapling.ext.github.pr_marker.cleanup_landed_pr_hook) spawns gh with a sanitized PATH (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin) that excludes /home/linuxbrew/.linuxbrew/bin where gh actually lives. Every draft commit's PR lookup raises FileNotFoundError, the hook returns 255, and sl pull propagates that.

Temporary workaround: apply in ~/.config/sapling/sapling.conf:

[github]
hide-landed-commits = false

Issue 2: sl metaedit doesn't work

It opens an editor as usual, but once I make edits, save and quit the editor, it exits again with 255, and the changes are not preserved. Might be related to munmap-segv-example/README.md but I don't know.
