Dear Kyle Jones:

I have read your opinion.  But, I'm still thinking that this feature is a bug.
There are two reasons why I think so.

First, let's try to see how 'isearch-backward-regexp' (not
're-search-backward') works.

Please open a empty buffer, and type 'a' <space> 'b' (that is, three
characters).  Now, the cursor is positioned at the end of the buffer.

Next, please invoke 'isearch-backward-regexp' and tyr to search regexps
"a\|b".  Watch out how the cursor moves.  It goes to 'a', returns back to home
position, finally goes to 'b'.

Though 'isearch-backward-regexp' and 're-search-backward' are somewhat
different functions (yes, the former is interactive while the latter
non-interactive), the experiment above implies the desirable feature how
regexps should work.

Secondary, you say

The Emacs manual (chapter 13.5 Syntax of Regular Expressions) says that the
text itself (ordinary character) is also regular expression, too.

Thank you.
