[Emacs-diffs] emacs-24 18a89a0 1/2: Better support for multi-line shell input.

[João Távora]

branch: emacs-24
commit 18a89a069c3d66ddb96e512f254f67f69d51ae22
Author: Juri Linkov <address@hidden>
Commit: João Távora <address@hidden>

    Better support for multi-line shell input.
    
    * lisp/comint.el (comint-history-isearch-search)
    (comint-history-isearch-wrap): Use field-beginning instead of
    comint-line-beginning-position.
    (comint-send-input): Go to the end of the field instead of the end
    of the line to accept whole multi-line input.

    [backport from trunk]
