Can you explain how/why the original causes "abort trap: 6"
(whatever it is) and how/why the updated one avoids it in the log
message?

It also is not quite clear when the error happens.  Do you mean, by
"non-git commands", something like:

    $ ca<TAB>

does not complete to "cal", "case", "cat", etc. and instead breaks
the shell?

I am confused.  The only change I can see in the patch is that it
makes the argument to this call to the __gitcomp shell function be a
string with tokens separated by LF and HT and no SP (the original
assumes that the tokens will be split by LF, HT or SP, and the shell
function locally sets $IFS to make sure that the change in this
patch does not make any difference).  And in many other places in
the same script, the __gitcomp shell function is called with an
argument with LF, HT or SP spearated tokens, e.g.

    _git_add ()
    {
            case "$cur" in
            --*)
                    __gitcomp "
                            --interactive --refresh --patch --update --dry-run
                            --ignore-errors --intent-to-add
                            "
                    return
            esac
