In order for this to happen the last line in the buffer has to start with "while" and must not be terminated with a newline. The following actions trigger this symptom for me when I start emacs using "emacs -Q": 1) Enable show-paren-mode by typing "(show-paren-mode 1)" and evaluating it with "C-x C-e". 2) Enable shell-script-mode by typing "(shell-script-mode)" and evaluting it with "C-x C-e". 3) Clear the *scratch*-buffer by first doing "C-x h" followed by "C-w". 4) Type the word "while". Other words might follow but the line might not be terminated with a newline. 5) Go to the begining of the line using "C-a". Afterwards emacs hangs. I can't move the cursor anymore. To quit this state I type "C-g C-g C-g". If afterwards I do "C-h l" I get: ( s h o w - p a r e n - m o d e SPC 1 ) C-x C-e ( s h e l l - s c r i p t - m o d e ) C-x C-e C-x h C-w w h i l e C-a C-h l If show-paren-mode is not enabled or the "while"-line is terminated with a newline, then the problem does not occur. Further I have the same problem with "if", "case", "for", "until". It is not necessary that the line begins with these keywords, e.g. "ls -1 | while read line". If I move the cursor to the beginning of this "while" I have the same problem (as long as the line is not terminated with a newline).
