When a remote is configured to be readonly, don't allow changing what's
exported to it.
This was missed in the original export remote implementation, but it makes
sense for a readonly export remote to not be allowed to change.
~/.profile works for bash, but not all other login shells.
This setting PATH is a minor convenience for users, particuarly since
typing on android is so much harder. The usual linux standalone bundle
just expects the user to know how to add it to PATH. I don't want this
code to grow special cases for every possible login shell. So displaying a
message to the presumably minority who don't use bash seems like the best
choice.
Longer term, I'd hope termux gets some way to set an environment variable
for all login shells. Systems using PAM can, via ~/.pam_environment. Or
alternatively, add a git-annex package to termux, even if just an installer
package. I'd rather spend time on either of those than on making this minor
thing support more login shells.

* init: When the repository already has a description, don't change it.
* describe: When run with no description parameter it used to set
the description to "", now it will error out.
Fixes bug that caused git-annex to fail to add a file when another
git-annex process cleaned up the temp directory it was using.
Solution is just to push withOtherTmp out to a higher level, so that
the whole ingest process can be completed inside it.
But in the assistant, that was not practical to do, since withOtherTmp runs
in the Annex monad and the assistant does not. Worked around by introducing
a separate temp directory that only the assistant uses for lockdown.
Since only one assistant can run at a time, it's easy to clean up that
directory of old cruft at startup.
