Merge branch 'fc/styles'

C coding style fixes.

* fc/styles:
  block-sha1/sha1.c: have SP around arithmetic operators
  base85.c: have SP around arithmetic operators
  archive.c: have SP around arithmetic operators
  alloc.c: have SP around arithmetic operators
  abspath.c: have SP around arithmetic operators
  alias: have SP around arithmetic operators
  C: have space around && and || operators
