Linus reported that the bash completion for git show often dropped
the ref portion of the argument (stuff before the :) when trying
to complete a file name of a file in another branch or tag.
Bj?rn Steinbrink tracked it down to the gvfs completion script
which comes standard on many Fedora Core based systems. That is
removing : from COMP_WORDBREAKS, making readline treat the entire
argument (including the ref) as the name that must be completed.
When the git completion routines supplied a completion of just
the filename, readline replaced everything.
Since Git users often need to use "ref:path" or "ref:ref" sort of
arguments, and expect completion support on both sides of the :
we really want the : in COMP_WORDBREAKS to provide a good user
experience. This is also the default that ships with bash as it
can be useful in other contexts, such as rcp/scp.
We now try to add : back to COMP_WORDBREAKS if it has been removed
by a script that loaded before us. However if this doesn't work
(as the : is stripped after we load) we fallback in the completion
routines to include "ref:" as part of the prefix for completions,
allowing readine to fully insert the argument the user wanted.
