New Revision: 212187
URL: http://svn.freebsd.org/changeset/base/212187

Log:
  sh: Add a test that 'read' leaves the file pointer at the correct place.
  
  Naive buffering would break the common while read x... construct, which did
  not appear to be tested yet.

Added:
  head/tools/regression/bin/sh/builtins/read2.0   (contents, props changed)

Added: head/tools/regression/bin/sh/builtins/read2.0
