        * Fix browser examine_directory() writable buffer parameter bug.
        
        Despite being "const char *", the directory "d" parameter was being
        modified inside examine_directory() if the directory no longer
        existed.  The code climbed the directory path until it found where it
        still existed, using the strchr() return value as "char *" to modify
        the "const char *" parameter.
        
        Unfortunately, it modified the buffer data directly without updating
        the dptr.  This could lead to buggy behavior, because subsequent
        buffer operations would append to the dptr, unaware that the string
        was nul terminated earlier.
        
        Thanks to Rene Kita for finding this issue and to Alejandro Colomar
        for his research into the problem.

        * Fix IMAP reconnect crash at password prompt.
        
        When waiting at a password prompt, eventually it will time out and
        call imap_keepalive().  This will end up recursively calling
        imap_check_mailbox(), because the idata has IMAP_REOPEN_ALLOW set
        during a reconnect operation.
        
        To prevent this problem, don't send keepalives on connections with a
        FATAL status.  In any case, we shouldn't be sending keepalives since
        the connection is in an unknown state.
        
        As an aside, a reconnect should be using the cached credentials in the
        Connections list when imap_conn_find() iterates through the connection
        list.  However, ticket 517 clearly shows there is a path where this is
        not happening.  I haven't figured out how yet, but this fix should be
        applied regardless.

        * Fix another compilation error --without-wc-funcs.
        
        This was generating an error on FreeBSD:
          mbyte.c:417:5: error: redefinition of '__wcwidth'
        
        Thanks to Daniel Tameling for suggesting the undef and testing it
        fixes the build error.

        * Fix iswblank() compilation error when configured --without-wc-funcs.
        
        The iswblank() call was added to mutt_format_string() in commit
        7074b571, more recently than all the mbyte.[ch] substitution code
        added about 25 years ago.
        
        Unfortunately, when added, it wasn't included in the HAVE_WC_FUNCS
        tests, and a replacement was not created in mbyte.c for when mutt is
        configured with --without-wc-funcs.  This led to a compilation error
        in that (apparently rarely used) configuration, because wctype.h is
        not included in that case.
        
        Honestly the code is a little bit confusing, but I've preserved the
        existing conventions for this stable branch fix.
