bug#2786: align-regexp -- no response

[박신일]

My system: Windows Xp SP3(32bit), ntEmacs 23.0.0.1 (i386-mingw-nt5.1.2600)

 

My file's content is like below.

Notice that the first character of the first line is a whitespace,

and the first character of the second line is not a whitespace.

 

 This is my text file.

This is my text file.

 

 

Aaginst this text, I gave a command.

 

M-x align-regexp RET

 

When minibuffer shows "Align regexp: ", I just struck Retern key without giving any regular _expression_.

And then Emacs doesn't response any more. Is this a bug?

 

Reproduction scenario

1. The first character of your file's first line begins a whitespace.

2. The first character of your file's second line begins a non-whitespace character.

3. After the M-x align-regexp command, just strike Return key without giving any regular _expression_.

 

Result: Emacs doesn't response any more. You should kill the process of Emacs.

 

Good luck to you all. Long live GNU, Linux, Emacs!!  :-)
