Subject: http.c: Use timeout suggested by curl instead of fixed 50ms timeout
X-Git-Tag: v1.7.8.1~13^2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=eb56c82163487fe07ba04f2b365a557282cbd766;p=git.git

http.c: Use timeout suggested by curl instead of fixed 50ms timeout

Recent versions of curl can suggest a period of time the library user
should sleep and try again, when curl is blocked on reading or writing
(or connecting). Use this timeout instead of always sleeping for 50ms.
