Subject: Get rid of uses of MAX_SHORT_STRING in Gnumeric and PostgreSQL readers.
X-Git-Tag: v0.7.3~74
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aaa1996142d111e34e13e490fb299bb94a73ed2f;p=pspp-builds.git

Get rid of uses of MAX_SHORT_STRING in Gnumeric and PostgreSQL readers.

MAX_SHORT_STRING is now intended to be an implementation detail of the
value code.  There is no real reason that the Gnumeric or PostgreSQL
readers need to use it, so make them use their own constants instead.
