Subject: escape: allow curl_easy_escape to generate 3*input length output
X-Git-Tag: curl-8_10_0~445
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9bfc7f923479235b2fdf0e8fdd8468c0786a369b;p=thirdparty%2Fcurl.git

escape: allow curl_easy_escape to generate 3*input length output

Instead of capping it to the 3 * CURL_MAX_INPUT_LENGTH. To allow users
to URL encode larger chunks of data.

Closes #14339
