Ctrl+R breaks `less' searches

Ctrl+R breaks `less' searches

Hi folks,

Use of Ctrl+R in a `less' search breaks the search unless one has already 
succeeded.

For example, I have a file with the word "book" on line 2.

Session 1:

/book
(it finds book)

Session 2:

/~Rbook
Pattern not found

Session 3:

/book
(it finds book)
<home>
/~Rbook
(it finds book)

This doesn't happen on Linux. IIRC my $LESS variable and .lesskey file are 
the same in both places.

I hope this makes sense,

1.7.3-1 fixed a lot of more important things, but unfortunately it didn't 
fix this one. A standard search must succeed before a ~R (Regex-off) search 
will succeed. So if I'm searching for something which requires regular 
expressions to be off, I'll never find it unless I first search for 
something that doesn't require Regex-off.

I sent the cygcheck output with the original report last week. Do you need 
another one?

Have fun,

No what you sent was fine.  You're covered unless someone requests more
data.

That's not a Cygwin problem.  I can reproduce this behaviour on Fedora
11 with less 429 as well.  Less 436 in Fedora 12 is apparently fixed.
