Re: filenames in error messages

[Karl Berry]

    If the file name comes from the portable set ([-_a-zA-Z0-9./], and
    probably a few others like + that are not required by POSIX), then
    ...

Yes.  This is what I plan to propose to rms.  I asked the W3 person who
originally wrote about this whole thing to get his feedback first.

    Should I go ahead and hack on a new quoting style in quotearg.c that can
    be used in this manner, adding "" around the string only if an escape
    sequence or quote_these_too character is encountered?

Please.

Thanks,
Karl
