Subject: dot/profile: Set `XDG_RUNTIME_DIR' if it looks relevant.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/profile/commitdiff_plain/9326a87fd936ef6d4f4ca492cb667a5b9f28d869?ds=sidebyside

dot/profile: Set `XDG_RUNTIME_DIR' if it looks relevant.

Without this, later `emacsclient' run from an SSH session can't find
the desktop session's Emacs server.
