characters, as for fancy colorized prompts.  This was nearly a direct
lift from bash-2.05b's lib/readline/display.c, per guidance from Chet Ramey.

Prompts may contain terminal control characters which, for
example, change the color, background, or style of the prompt
text, or change the title of the terminal window. In order for
the line editing features of readline to work properly, these
non-printing control characters must be designated as invisible
by surrounding them with <literal>%[</literal> and
<literal>%]</literal>. Multiple pairs of these may occur within
the prompt. For example,
<programlisting>
testdb=> \set PROMPT1 '%[%033[1;33;40m%]%n@%/%R%[%033[0m%#%] '
</programlisting>
results in a boldfaced (<literal>1;</literal>) yellow-on-black
(<literal>33;40</literal>) prompt on VT100-compatible, color-capable
terminals.
