[pcre-dev] PATCH: remove push_back (was Re: Compile error?)

It turns out there's no real reason to prefer push_back() to append()
or operator+=() (see, eg
http://www.velocityreviews.com/forums/t287060-stdstringpushback-vs-stdstringoperator.html).
So I've changed the push_back calls to use += instead, which may give
us a bit more portability. Philip, can you apply this when you get a
chance? Patch below.
