--- Comment #2 from James E Keenan <jamesekeenan at yahoo.com> ---
Are there any plans to develop a workaround for this problem for FreeBSD-11 and

This came up for me -- a relatively new FreeBSD user -- when I went to use the
same assignment to $PS1 in my .shrc on a F11 VM as I had used for several
months on a F10.3 VM.  The problem was reported to the freebsd-questions
mailing list in the thread starting here: 

At first I assumed the problem was due to (a) difference between VirtualBox and
VMware; and/or (b) my own ignorance.  But as to (b):  I've been setting up
colored characters in my command-line prompt on Unix-like OSes since 2001.  And
a contributor to that thread indicated he was having the problem in a "bare
metal" environment

For reference:  uname -a
FreeBSD kid51.freebsd11 11.0-RELEASE-p1 FreeBSD 11.0-RELEASE-p1 #0 r306420: Thu

I can appreciate that, from one major OS release to the next, there need to be
improvements in basic libraries that can have undesired side effects.  But,
come on -- people have had color in their prompts for decades.  Why give it up
now?  This is clearly a regression in user-friendliness.

What will it take to develop a workaround?

Thank you very much.
