Tom Lane 1e5a5d03da Simplify some long-obsolete code in hba.c's next_token(). next_token() oddly set its buffer space consumption limit to one before the last char position in the buffer, not the last as you'd expect. The reason is there was once an ugly kluge to mark keywords by appending a newline to them, potentially requiring one more byte. Commit `e5e2fc842` removed that kluge, but failed to notice that the length limit could be increased. Also, remove some vestigial handling of newline characters in the buffer. That was left over from when this function read the file directly using getc(). Commit `7f49a67f9` changed it to read from a buffer, from which tokenize_file had already removed the only possible occurrence of newline, but did not simplify this function in consequence. Also, ensure that we don't return with *lineptr set to someplace past the terminating '\0'; that would be catastrophic if a caller were to ask for another token from the same line. This is just latent since no callers actually do call again after a "false" return; but considering that it was actually costing us extra code to do it wrong, we might as well make it bulletproof.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	http://www.postgresql.org/download

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
