[yocto] archiver.bbclass: do_dumpdata - shell format

[Tomasz Dziendzielski]

>From the bitbake/lib/bb/data.py:
"""Emits all items in the data store in a format such that it can be
sourced by a shell."""
so if you say it's shell-like, not shell, shouldn't we replace that to
"""Emits all items in the data store in a shell-like format"""?
If it cannot be sourced the statement "can be sourced by a shell" should be
removed.

So is there any proper parser to source this?

Best regards,
