|
2012-09-30 05:27:18 -03:00

|
only once. Before, the type function was called twice in the case where the
|
|
|
|
|
default was specified and the argument was given as well. This was especially
|
|
|
|
|
problematic for the FileType type, as a default file would always be opened,
|
|
|
|
|
even if a file argument was specified on the command line.
