[PATCHv3 0/4] clone: respect configured fetch respecs during initial fetch

This is a reroll of sg/clone-refspec-from-command-line-config. Sorry for the delay, family visit.

The first patch is the updated version of what is now the first commit of that topic. The changes are those mentioned in [1]:

 - updated commit message,
 - renamed 'refspec_count' to 'refspec_nr',
 - use the parsed fetch refspecs returned by remote.c:remote_get()
   instead of parsing them ourselves (look at the third hunk of the
   diff of builtin/clone.c, how much shorter it looks),
 - modified tests to check that refs matching the default refspecs are
   transferred as well, and
 - added a test for the combination of '-c
   remote.<remote>.fetch=<refspec> --origin=<name>'.

The second patch is a doc update to warn users that not all configuration variables are supported via 'git clone -c ...' at the moment.

Patches 3 and 4 are the last two patches from Peff from this morning [2]. I picked those up, because his last patch required a bit of variable name adjustments. I didn't pick up his first patch, because using remote_get() already factors out refspec parsing.
