git filter-branch

[mbojan]

Can we have R layer function for git filter-branch?

On the command line git filter-branch can be used, among other things, to filter e.g. commit messages through a shell script. With littler or Rscript it is possible to write such scripts in R. However, it incures quite an overhead as for each commit the script is executed independently (so time is spent on starting R, loading packages and so on). It would be great to be able to filter branches within a single R session using a function. Would that be possible?
