 The remaining are, 

```
pandas.ExcelWriter: Parameter ".. versionadded" requires a space before the colon separating the parameter name and type
pandas.core.groupby.DataFrameGroupBy.boxplot: Parameter "subplots " requires a space before the colon separating the parameter name and type
pandas.set_option: Parameter "value " requires a space before the colon separating the parameter name and type
``` @gfyoung  The remaining cannot be done as fixing them  introduce trailing  spaces. thanks @srinivasreddy
