Bash Version: 4.1
Patch Level: 5
Release Status: release
Description:
Using reverse video is PS1 causes bash to get confused when doing command line
editing.
Repeat-By:
The following sequence will reproduce the error. Note that the file name must
be
longer than 7 characters.
First, set the prompt string to use reverse video:
PS1="\e[7m\h:\w>\e[0m "
Next, set up a file we can use for completion:
echo >foobarbaz.txt
Finally, this input sequence will demonstrate the bug:
ls foo<TAB> foo<TAB> <control-A>
Instead of moving the cursor to the beginning of the line, the <control-A>
moves it
to the "r" in the forst "foobarbaz". Typing <control-L> to redraw the line
leaves
the cursor in the same erroneous place.
Note: the above works correctly in tcsh. It's a bash-specific bug.
