Suggestion for regtool

[DJ Delorie]

No, just a simple backslash checker:

for (sp=dp=buf; *sp; sp++)
  if (*sp == '\\')
    *dp++ = *++sp;
  else if (*sp == '/')
    *dp++ = *sp;
  else
    *dp++ = *sp;

I just want the meaning of '\\' to not be dependent on the character
following it.  I hadn't thought of adding codes for newline etc, but I
can see how that would be useful.  What does bash support?

Another option is to use HTTP or MIME quoting, like %30 is a '0' or
=45 for 'E'.  I'm not sure which would be more "natural" for cygwin
users.
