Log Message:
-----------
sv.c - add support for SVfQUOTEDPREFIX for error messages.
This new format is intended to be used in error messages where
we want to show the contents of a string without any possible
hidden characters not rendering in the error message, and where
it would be unreasonable to show every character of the string
if it is very long.
A good example would be when we want to say that a class name is illegal.
Consider:
"Foo\0"->thing()
should not throw an error message about "Foo" being missing, the fact there
is a null in there should be visible to the developer. Similarly if we had
("x" x 1000_000)->thing()
we also wouldn't want to throw a 1MB error message. Currently this
patch restricts it to the first 1000 characters, but the docs are such
that we can reduce that if we wish, I suspect something like 100 would
be more reasonable.
Example usage:
other= newSVpvs("Some\0::Thing\n");
sv_catpvf(msg_sv,"%" SVfQUOTEDPREFIX, SVfARG(other));
Should append
"Some\0::Thing\n"
to the msg_sv. If it were very long it would have elipses suffixed:
"long string...truncat"...
This will be used in a following commit.

Changed paths:
M universal.c
Log Message:
-----------
universal.c - use the shiny new SVfQUOTEDPREFIX for the error message
And at the same time avoid saying the package name twice. Whats the point
of that?
