I'm attaching the test case "source.sh", but I'm not sure if user meant
this. The report is too hazy.

Your test case worked fine under mksh.

Forgot to mention it, yes. The test case passed, the directory name was
completed correctly
mkdir 'Whiteboards & Photos'
cd W[TAB]
cd Whiteboards\ \&\ Photos/

Same problem in mksh. I've contacted the developer about this.

We could use both, but have /usr/bin/ksh to point to one that has proven
the most ksh compatible and bug free.
