[patch] get_sql_initial_data_for_model can't handle quoted quotes

[eaw@…]

The RE in get_sql_initial_data_model can't parse data of the form 'Susan O\'Brien' properly (it ends up generating invalid SQL), so I've taken the approach of simply splitting the initial data into separate SQL statements where ";[ \t]*$" occurs (i.e. a ; at the end of line). [This definition of a statement probably needs to be documented.] Here is the svn diff of the change:

Patch to split initial sql data into statements by ";"

[Adrian Holovaty]

(Fixed formatting in description.)

[jpellerin@…]

This is much better than my original patch. Easier to understand and more correct.

[Malcolm Tredinnick]

(In [3178]) Fixed #2119 -- fixed problems with splitting SQL statements into separate
statements. Uses a patch from eaw@… and some contributions from
jpellerin@…. Also fixes #2034 and #1935.
