[WAS-MY-MISTAKE] Pacman's regex behavior with plus symbols

Question

I think this is best explained with examples.
There's a 'libxml++' package in official repositories. It doesn't find it if I do this:
pacman -Ss ^libxml\+\+$
Even if I use no caret and/or dollar sign. It finds 'perl-xml-libxml' if I do this:
pacman -Ss libxml\+\+$
Which is really strange. And if I do this:
pacman -Ss gtk-++
It finds all 'gtk-.*' packages.
I know there was a bug saying that devs should make pacman search regex-like and non-regex-like when it comes to pluses, but at the moment the regex way isn't working properly.
Is this a bug, or was support for regex pluses completely dropped? If yes, how would one search for exact match with string that contains pluses?

your escapes are not working properly. try:
pacman -Ss ^libxml\\+\\+$
or, more generally:
pacman -Ss '^libxml\+\+$'
