One more I found - line 843. I quoted the echoed PROMPT_COMMAND for

I had to use single-quotes to get it to work. I tried escaped double-
quotes but I still got path splitting errors. I decided not to
commit this myself, in case the single quotes cause other problems
(that fine detail is beyond my shell knowledge).

Any opinions on this?

bash parses $PROMPT_COMMAND, so you need yet another level of quoting.

I suspect that you want:

  echo PROMPT_COMMAND="\''$GISBASE/etc/prompt.sh'\'"
