Does pigeonhole regex extension support PCRE?

[Lev Serebryakov]

I've tried to use negative look-ahead in :regex match like this:

if header :regex "List-Id" "<svn-([^-]+)-(?!all)([^.]+)\.freebsd\.org>"
{ ... }

and manage-sieve server complains on save about such regex with
diagnostic "repetition operator operand invalid" :(
