[PATCH 1/4] remote: use skip_prefix

[Thomas Gummerer <t.gummerer@gmail.com>]

95b567c7 ("use skip_prefix to avoid repeating strings") transformed
calls using starts_with() and then skipping the length of the prefix to
skip_prefix() calls.  In remote.c there are a few calls like:

  if (starts_with(foo, "bar"))
      foo += 3

These calls weren't touched by the commit mentioned above, but can
benefit from the same treatment to avoid magic numbers.
