Subject: urldata: make redirect counter 16 bit
X-Git-Tag: rc-8_17_0-2~73
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f8cd64e3abaae0ea7289c380362571060d0a1160;p=thirdparty%2Fcurl.git

urldata: make redirect counter 16 bit

Instead of long (up to 64-bit) as the maximum allowed value set since
b059f7deaf3 is 0x7fff. Saves 2 or 6 bytes.

Closes #19072
