Subject: here-document syntax inference and completion is broken
Date: Tue, 05 May 2009 15:15:00 -0700

Steps to reproduce:

Cook yourself up a bash script and type a line of code like:
for i in $(/bin/vim <<

A default emacs install will complete with "EOF\n\nEOF" (in a more 
clever fashion so the rest of the line is undisturbed), and place the 
cursor on the new blank line.  This is
incorrect behaviour, as it breaks entry of BASH here-strings when the 
user's intent is still ambiguous.  This should only respond to things 
ending in, for example "<< " or
possibly "<<E", but certainly NOT just "<<".  Further, emacs does 
something outright wrong:  An attempt to fix the situation by inserting 
another '<' between the "<<" and "EOF" +results in ANOTHER pair of "EOF" 
being inserted in a syntactically invalid way.
