[Gretl-devel] misc bug fixes

Current CVS and all snapshots now contain fixes for the following recently reported bugs: * Functions such as obsnum() which expect a string argument were failing when the argument was given in the form of a function that returns a string. See http://lists.wfu.edu/pipermail/gretl-devel/2013-August/004588.html * When python code is embedded in a gretl "foreign" block within a user-defined function, indentation of the python code was not being respected. See http://lists.wfu.edu/pipermail/gretl-devel/2013-August/004579.html * In the context of the ternary query operator (as in "condition ? true_branch : false_branch") the presence of an undefined symbol was generating an error, even if this symbol was confined to the non-selected branch. See http://lists.wfu.edu/pipermail/gretl-devel/2013-August/004598.html * The "modeltab" command with the --output=filename option was not working properly unless "modeltab show" was executed first.
