write_tsv doesn't allow for specifying the decimal separator

[deschen1]

I want to export some data with TAB as the column delimiter (for which reason I'm using write_tsv(), however, I can't specify a decimal separator, which (in my case) makes it difficult to import to Excel using a German locale, because the default decimal separator in R/write_tsv is a ".", whereas certain European countries use ",".

Is there any option to specify the decimal separator for write_tsv() or would that be an option to add?
