bug#30595: [PATCH] Handle command line wrapping in Tramp adb.

[Mathieu Othacehe]

The command sent to an adb shell input might be wrapped around
terminal column count by the kernel. Remove CR and LF introduced when
it happends.

* lisp/net/tramp-adb.el (tramp-adb-send-command): Remove W32 trailing
  CR but also CR/LF introduced by command line wrapping.
