bug#29149: Tramp shell uses local shell setting in windows

[Shuguang Sun]

Hi Michael,

I attached the trace log which has actions: open the file coxph_bench.r, and edit it, and save it. If you need the full log, please let me know.

Occur: c:/\|drive my help.

Looks like something of "| | | | | | 7 -> (tramp-drop-volume-letter "c:/opt/home/username/test/coxph_bench.r")" was not applied.

Since I cannot test under MS Windows, I need traces. Shuguang, could
you, pls, apply the settings as described in the Tramp manual, at the
bottom of (info "(tramp) Traces and Profiles") . Rerun your tests,
provoking a remote backup file. This produces a buffer *trace-output*,
which should tell us where the mysterious !drive_c! is prepended.

Best regards, Michael.
