Pattern translator does not escape special characters correctly.

[paulcuth]

The following example highlights differences in output of pattern matching functions between C Lua and Moonshine.

print(string.gsub('ReturnRegionNotification', '\\u.?.?.?.?', 'XXX'))

C Lua returns:

ReturnRegionNotification    0

Moonshine returns:

RetXXXgionNotification  1

I believe there's some escaping of special chars missing from the translated pattern prior to construction of the RegExp object.

I just ran into the same problem. Here are two examples:

s = "-"
print(string.match(s, "%-"))
output: userdata (should have been "-")

s = "-2"
print(string.match(s, "%-%d"))
output: 2 (should have been "-2")

The pattern matching seems to be having trouble with the minus sign. The %d seems to work ok.

These pattern matches work fine on my regular Lua.
