-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This bug is insidious, as there is more than one wrong string printed to the display. For example, this screenshot shows that the original prompt doubles the last prompt character ($), but after tab completion has displayed a list, it doubles the first user-character (a). From there, using the arrow keys to go back, then forward in history, corrects the display:
$ PS1='\[\e]0;1\a\]$' $$a[TAB] a/ am4tPD2876/ atrace.dll a2p.exe amcompat.tlb attrib.exe ... alrsvc.dll atobm.exe $aa[UP] $aPS1='\[\e]0;1\a\]$'[DOWN] $a[UP] $PS1='\[\e]0;1\a\]$' Also, someone on the cygwin mailing list suggested that a workaround is to fake bash into thinking that the last invisible character is the last prompt character: PS1='\[\e]0;1\a\]$\[\]' This solves the problem of the initial prompt, but not the display after tab-completion. And it points out a flaw in the readline expand_prompt() logic for letting a zero-length \[\] invisible character marker pair change the *lip parameter to an index of a non-invisible character. - -- Life is short - so eat dessert first!
