CVS commit: src/bin/sh

["Christos Zoulas" <christos%netbsd.org@localhost>]

Module Name:    src
Committed By:   christos
Date:           Sun Nov 14 19:43:38 UTC 2010

Modified Files:
        src/bin/sh: parser.c

Log Message:
- Fix a couple of bugs to make the following two echo statements print the
  same output as they should:

    line='#define bindir "/usr/bin" /* comment */'
    echo "${line%%/\**}"
    echo ${line%%/\**}

1. ISDBLQUOTE() was not working properly for non VSNORMAL expansions because
   varnest was incremented before the variable was completely parsed. Add
   an insub adjustment to keep track of that.
2. When we have a quoted backslash, we need to escape twice, because one
   level of escaping will be stripped later. (XXX: Do that when insub == 1
   only?)

- Make macros statements
