Colour prompt fowls line wrapping (2.04.11(1))

[Simon A Watts]

Using a new installation of RH 7.0, which has Bash 2.04.11(1) (bash 
--version).

I have tried setting my PS1 prompt to display in white, so that it is 
obvious where program output starts:

PS1='ESC[1;37m[\u@\h \W]\$ESC[0m '   

Where ESC is typed CTRL-V,ESC, or character 0x1B.  (This could also be 
[\033?).

This has the effect of setting the font for the prompt to bright white, 
on my usual green-on-black console.

This screws the wrapping of the command line:

1.    Wrapping starts well before the right hand edge of the terminal 
(is it counting the control characters?).
2.    When it wraps, it performs a 'return' but not a 'line feed'.  The 
cursor goes to the start of the line and overwrites (including the prompt).
3.    If I now left-arrow (or backspace) along the command line, it does 
perform an "inverse-return" and "inverse-line-feed", so the cursor is 
now on the line *above* where I started.  Things get pretty confusing 
from this point on...

This is a great pity, as I rather like the command prompt to be 
outstanding, as I can clearly see where the boundaries between command 
o/p are.


Si.
