Hello,
I use ./bash 4.3.42 with bundled libreadline and
git/contrib/completion/git-completion.bash , as modified by commit
8716bdca268 from 22 Feb 2016.
I cd to git.git (non-bare, with working tree) and type
git b62c.. ori<TAB> to force TAB-completion. And then on the shell comes
the output (on the same line) "error: key does not contain variable
name: alias.b62c.." Pressing again TAB repeats the message. Even if
TAB is pressed once, the printed text cannot be deleted with the
backspace, so the only way to do something useful is to press ENTER.
While the command is indeed nonsense, in my understanding tab-completion
shall do nothing, if completion is not possible. In particular it shall
not print error messages and even the user types stupid things, he shall
not be required to force ENTER to come back to a clear state, where a
command can by types.
Greetings
Dilian
