Subject: Change signature of text_to_value.
X-Git-Tag: build37~44
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d8659cda7d193dd3e6e035cd0b1b40493d360f0b;p=pspp-builds.git

Change signature of text_to_value.

Now, text_to_value initialises the value, and expects
the caller to destroy it.

This fixes some gui bugs where strange things happened with long string
value labels and missing values.
