Because we checked the limitation of raw+sparse during command line
|
|
|
e9bfca |
processing, it had the effect of forcing you to use ‘-of raw’ even if
|
|
|
e9bfca |
the input was already in raw format. Move the checking to the output
|
|
|
e9bfca |
mode to avoid this.
|
|
|

|
|

Fixes commit cc04573927cca97de60d544d37467e67c25867a7.
