This is not really a bug, but a small usability problem.
When completing a reference, Bash will add a space after the reference name.
As an example in:
$git show master<TAB>
The problem is that an user may want to show a tree or blog object from
master:
$git show master:git.c
Or the user may want to see only changes to the documentation, e.g.
$ git show master Documentation/
so removing a SP is a regression in the other way around.
Given that "refer to an object in a tree" is a much less often used
operation, I have a feeling that the current behaviour happens to
make a good trade-off between these two conflicting purposes that
cannot be satisfied both at the same time.
