The plural in the suggested function name was intentional on my part,
even though in this callsite in question we are only interested in the
filename, i.e. only a single path component.

I was hoping that the names of these related functions will be kept in
sync, and all will somehow contain the "path_components" substring,
e.g. strip_path_suffix() becomes strip_suffix_path_components() or
something.  And that function must be able to handle multiple path
components, becase there is this callsite:

  exec-cmd.c:         !(prefix = strip_path_suffix(executable_dirname, 

and the build sets '-DGIT_EXEC_PATH="libexec/git-core"' by default.
