Subject: Fix erroneous error message printout when a configuration file contains
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=9544d69131ee5f3c2d17652dd965c064c4749f80;p=users%2Fbernd%2Fpostgres.git

Fix erroneous error message printout when a configuration file contains
an overlength token.  Printout was always garbage and could dump core
entirely :-(.  Per report from Martin Pitt.
