Subject: [PATCH] Bug 11630: improve parsing of age restriction markers
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This patch makes the parsing of AgeRestrictionMarker values consider
the case where the marker is immediately followed by the age, e.g.
"K16" in Finland.

How I tested:

[1] Configure Age Restricition (see Syspref AgeRestrictionMarker) and
have a biblio record with e.g. PEGI 99 in age restriction field.
[2] Try to check out to a patron with age < 99
[3] Check out should be blocked
[4] Change entry in age restriction field to PEGI99
[5] Checkout should be possible
[6] Apply patch
[7] Checkout schould now be blocked
