bazel

Description of the feature request:

For better bash-less Windows support,ctx.actions.run_shell could add command_bat (with the same behavior as genrule's cmd_bat) and command_ps (with the same behavior as genrule's cmd_ps).

This would, in particular, considerably simplify skylib's Windows support, where currently we are forced to write and execute temporary .bat files on Wind

With #11315 done, we can do some small optimizations:

• NonEmpty
  • if it makes a difference, redefine pour to abstract over IterableFactory and MapFactory, if those implementations do optimization for same-type conversions
  • redesign pour's API to put the factory type first, no more tricky currying, #11933
  • just use toSeq for toSeq, #11933
  • define `coll

Since bazelbuild/rules_rust#612 we test more stuff on Windows, we don't test everything though. //test/rustfmt is currently disabled in .bazelci/presubmit.yml.

Feel free to comment on this issue if you want to know more or you want to give it a shot. We are happy to talk or help :)

How to fix when you don't have a Windows machine:

1. delete the line with ` - "-//t

See if we can replace sanitize_string_for_usage with code from skylib (existing or to contribute back).
Motivation for generalization- Recurring pattern of sanitizing inputs
