yup.

works. (Add vector->SQL Query)

works. (just another Tcl startup menu like all the rest)

still broken:
can not find channel named "couldn't execute "nviz2.2_script": no such
file or directory"


> I don't remember running into this in 5.3,

It was a problem in 5.3, but without the SQL queries it only affects the
d.text modules AFAIK. Fixed in CVS. Both the 5.3 and 5.7 changes make
the shell command preview un-cut&paste-able for things with spaces in
them, but this never worked before either.. some fancy formatting before
printing the text string could probably move & replace the {}s to "s if
someone was keen to try.


The error is still in  grass51/gui/tcltkgrass/main/gui.tcl  but that is
in now unused code which should be ripped out???
