FindMarkers fc.name does not yield the expected output

[igordot]

I tried using the FindMarkers() or FindAllMarkers() fc.name parameter in Seurat 4.0.1, but it does not seem to have any effect:

> library(Seurat)
Attaching SeuratObject
> data("pbmc_small")
> markers <- FindMarkers(object = pbmc_small, ident.1 = 2, fc.name = "xxx")
  |++++++++++++++++++++++++++++++++++++++++++++++++++| 100% elapsed=00s  
> head(markers)

The fold change column in still avg_log2FC. Is this expected behavior?

This should now be fixed on the develop branch
