Adriaan de Groot c3f366ce9e CI: check translations against detached branches
To avoid git complaining about duplicate worktrees, detach
the temporary trees. To avoid python modules translations
changing order (depending on how find traverses the tree),
sort the filenames before extraction.

### USAGE
#
# Does the translation tag (from a previous txpush) exist?
# This assumes that the release host has also locally done
# a translations push, which works for the current development
# workflow .. but it could be improved by looking for one of
# the typical txpush log messages instead of the tag.
#
# Use --cleanup as an argument to clean things up.
#
# Normal use:
# $ sh ci/txcheck.sh
# If there are differences, fix them and then clean up:
# $ sh ci/txcheck.sh --cleanup
#
### END USAGE
# The files that are translated; should match the contents of .tx/config
TX_FILE_LIST="lang/calamares_en.ts lang/python.pot calamares.desktop"
### COMMAND ARGUMENTS
#
# We need to define tx_cleanup for the --cleanup argument, although it's
# normally used much later in the script.
