I've just upgraded pcre (Perl-compatible regular expression) library
from version 8.12 to version 8.13 in F17.

Upstream says:

So the library itself should be fully compatible.

In addition, I've splitted bundled command line tools (pcretest and
pcregrep) to standalone sub-package `pcre-tools' and compiled them
against libreadline which makes interactive development of regular
expressions in pcretest more friendly.

Thus if your package utilizes one of the two tools, please change dependency
from `pcre' to `pcre-tools' or depend on the binary explictly. If this
is due to pcregrep, you can consider using grep with `-P' option
instead which is linked against pcre library either.
