The threee tags `<name>`, `</name>` and `<command>` were frequently used
with a leading space that this removes. The reason this habbit is so
widespread in testcases is probably that they have been copy and pasted.
Hence, fixing them all now might curb this practice from now on.
Closes#12028
This is already how curl is documented to behave in Everything curl, but
in actuality only short POSTs skip this. This should knock 30 seconds
off a full run of the test suite since the 100-continue timeout will no
longer be hit.
Closes#10740
Prior to this change if there was a 303 reply to a PUT request then
the subsequent request to respond to that redirect would also be a PUT.
It was determined that was most likely incorrect based on the language
of the RFCs. Basically 303 means "see other" resource, which implies it
is most likely not the same resource, therefore we should not try to PUT
to that different resource.
Refer to the discussions in #5237 and #5248 for more information.
