file tagging runs slow for large tarballs (e.g. php and git)

A big part of the problem is dealing with 'funny' file names out of find.
@dougburns has fixes that work and are likely the best we can do with what we have.
BUT I saw this: https://explainshell.com/explain?cmd=find%20.%20-type%20f%20-print0
Too bad our 'find' doesn't support -print0, nor does our xargs (BUT - we can port these...)

IF we had a modern find and xargs then we could more efficiently process file names with odd characters using the -0 options on find and xargs.

@dougburns @IgorTodorovskiIBM fyi....

@dougburns @IgorTodorovskiIBM now that find, xargs, sed are working pretty well, perhaps we can 'pre-req' them (along with git, curl) and then change the code to use them?
@IgorTodorovskiIBM maybe we don't need it anyway because of the enhancements you've made to git?
