CVS commit: src/bin/sh

Module Name:    src
Committed By:   christos
Date:           Tue Nov 16 18:17:32 UTC 2010

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

Log Message:
PR/43469: Antii Kantee: test/util/sh/t_expand:strip fails.
Bring back fixes from revision 1.75:

- 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 either need to escape twice, because
   one level of escaping will be stripped later (in the variable substitution
   case) or simply enter the backslash.
