New Revision: 268436
URL: http://svnweb.freebsd.org/changeset/base/268436

Log:
  sh: Add test for ${01} and ${010} that already works.
  
  Although it is probably unwise to use this, POSIX is clear that leading
  zeroes are permitted in positional parameters (and do not indicate octal).
  
  Such positional parameters are checked for being unset and/or null
  correctly, but their value is incorrectly expanded.

Added:
  head/bin/sh/tests/parameters/positional3.0   (contents, props changed)
Modified:
  head/bin/sh/tests/parameters/Makefile
