Summary:                    [patch] Introduce better parsing for the register
line
Description: 
People have asked for the ability to use characters that are otherwise used
as delimiters in the register line, such as '/', '@', and ':'.  In the
past, we've had to say no, because the register line is very simply
parsed.

This patch allows any part of the register line to be quoted, and the
section within the quote may contain any of these special characters. 
Literal quotes and literal backslashes may be added to these fields by
prefixing them with a backslash.  Also, if no quotes are used around a
particular field, the delimiter character may be preceded with a backslash,
to encode that literal character within the field.
