Subject: Allow variables to be entered beyond the end of sheet.
X-Git-Tag: v0.7.1~71
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?p=pspp-builds.git;a=commitdiff_plain;h=4e353bce75f100fb7d9b2dc1fa26bcf4e8ca2679

Allow variables to be entered beyond the end of sheet.

Several changes to fix the problem where variables beyond
the vertical size of the var sheet couldn't be added.

1. Undo the effect of commit 8c9fae384585163197685e684e62e49a6b922f0c
since it seems to cause problems and need to be rethought.

2. On the traverse callback, don't clamp the range of the requested
   destination cell.  Clamp it only after the signal returns.

3. Add one more row than there are variables.
