[issue3343] Py_DisplaySourceLine is not documented

[Amaury Forgeot d'Arc]

New submission from Amaury Forgeot d'Arc <amauryfa at gmail.com>:

This new function is not documented at all.
And I find the error handling not consistent: when filename is NULL, -1
is returned, but no exception is set.

IMO the return code should be as follow:
- return 1 if a line was printed
- return 0 if the line cannot be found
- return -1 in case of error (when calling PyFile_WriteString); an
exception is set.
