repeat isearch-forward-regexp with just C-s C-s also

[Dan Jacobson]

ESC C-s runs the command isearch-forward-regexp

OK, but to repeat the last regexp search, another ESC C-s C-s seems
too much to ask.  How about just C-s C-s?  I.e. make C-s C-s will
repeat the last search, be it plain or regexp.  Make this behavior a
new option turned on by default.

<escape> C-s i $ C-s C-s C-e m <escape> C-s C-s C-s C-s
                               ^^^^^^^^pain in the brain,
I don't know why, but it is.  Indeed, (grep "grep -n -e i$
exercises0.in") and next-error is one million times less painful.

I am not sure it is a good idea for C-s to do a regexp search.
Repeating the last non-regexp search, which is what it does now,
seems like the right thing to do.

But if users want to try it and report their opinions,
I'd be interested in hearing about it.

I've been using a local patch which makes C-s C-s repeat the last search
(regexp or not) and I find it very useful.  The problem is that I find
M-C-s M-C-s significantly more difficult to hit than C-s C-s, so when
I need to repeat a search many times, C-s C-s is much better.
Another reason is that I rarely use M-C-s but instead I do
`C-s ..blabla.. M-r ..blibli' because I often notice "too late" that I want
a regexp search rather than a plain search, so almost all my regexp
searches are started with C-s rather than with M-C-s or C-u C-s.
