tramp-cache and destructive operations

[Jürgen Hötzel]

Hi,

for example 'eshell-ls-sort-entries' uses `sort' and thus the tramp cache is modified by side effects.

This results in invalid eshell-output (at least when using tramp-adb):

  /adb:root@:/mnt $ ls

  asec  media_rw  obb  sdcard  secure  shell

  /adb:root@:/mnt $ ls

  shell

As a workaround I use `copy-sequence' in `tramp-adb-handle-directory-files-and-attributes'.

But this is not a generic solution. Should tramp-cache be modified to always return a copy of lists?

Thanks,

Jürgen
