            Bug ID: 16059
           Summary: wordexp(3) -- A[0]='a b' gives error
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: opengeometry at yahoo dot ca
                CC: drepper.fsp at gmail dot com

Hi, I'm not sure if it's bug or just misunderstanding.  Given two
similar cases,

    wordexp ("one:  A[0]='a b'  end", &w, 0);   --> error=5 (WRDE_SYNTAX)
    wordexp ("one:  'A[0]=a b'  end", &w, 0);   --> ok

the result should be 3 strings,

    one:
    A[0]=a b
    end

just like shell.  Yet, I get error for the first case.  I think
wordexp() is getting confused about glob [0] which is followed by
<single-quote> and then <space>.

Could you send this also to libc-alpha. You need also add changelog like
following one

2010-10-14  Random Developer  <developer@provider.com>

        * posix/wordexp.c (wordexp): Fix whitespaces inside quoted string.

There are a lot of problems with quoting in wordexp parsing.

- quoted glob meta characters need to be requoted for glob, but the result must
undergo quote removal if no file was matched
- unterminated quoting needs to be diagnosed
- the check to distinguish $((foo)) from $((foo);(bar)) doesn't handle quoted
parens
- parse_comm doesn't handle backslash quoting
