You're proposing two separate functions:
1) quoting of non-wildcard specials
2) quoting of wildcard specials
The trouble with this is that, instead of offering extra functionality, it
leaves the door open to making two stupid mistakes:
1) quoting of wildcards WITHOUT quoting of non-wildcards
2) quoting of wildcards BEFORE quoting of non-wildcards
There are only two non-stupid solutions to this problem that I can see.
Either:
* A pair of functions that perform
1) quoting of non-wildcard specials only
2) quoting of both non-wildcard and wildcard specials
Or:
* A single function that performs either of the above two operations,
depending on a boolean flag--which is what QuoteSQL does.
I guess I don't have a strong preference for which way we do it, but I would
suggest confining our discussion to non-stupid solutions.
