<pre>This is observable in any file produced by obj2yaml, and is annoying when
checking in test YAML test cases. Git and other tools complain about trailing
whitespace, and it would be great if we could silence that without manually
removing the whitespace.
The bug is in Output::preflightKey, which pads out the column after emitting
the key name:
bool Output::preflightKey(const char *Key, bool Required, bool SameAsDefault,
bool &UseDefault, void *&) {
UseDefault = false;
if (Required || !SameAsDefault || WriteDefaultValues) {
auto State = StateStack.back();
if (State == inFlowMapFirstKey || State == inFlowMapOtherKey) {
flowKey(Key);
} else {
this->newLineCheck();
this->paddedKey(Key);
}
return true;
}
return false;
}
If there is no value or the value flows onto the next line, the padding
whitespace is left behind trailing.</pre>
