It's a feature, though it doesn't appear to be documented in the Emacs manual:
| search-whitespace-regexp's value is "\\s-+"
|
| Documentation:
| *If non-nil, regular expression to match a sequence of whitespace chars.
| This applies to regular expression incremental search.
| You might want to use something like "[ \t\r\n]+" instead.
| In the Customization buffer, that is `[' followed by a space,
| a tab, a carriage return (control-M), a newline, and `]+'.
You need to type `C-s C-q SPC ? t', or set search-whitespace-regexp to nil.

GNU Emacs 21.3.50.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 2003-06-24 on localhost.localdomain
While searching for " ?t" regular expression, letter 't' in word
"reset" doesn't match. This is very strange since searching for
"t?t" and even "^I?t" does match the letter. Is it "a feature"
or a bug somewhere in Emacs?

Wouldn't it solve the problem if `search-whitespacec-regexp' was set
to "\\(\\s-+\\)" by default? Or would it break something match group
related?
And, btw, i'm not subscribed to the list. Could you please CC answers
to me?
