[PATCH 0/2] Improve line log documentation

["Philippe Blain via GitGitGadget" <gitgitgadget@gmail.com>]

These two patches add more information to the documentation for line history
(git log -L) : 

 * Mention explicitly that only the --patch and --no-patch diff formats are
   supported 
 * Mention that any given regex must match in the starting revision

Regarding point 2 : I stumbled upon this while reading the history of
'filter_refs' in fetch-pack.c. I did

    git log -s -L :filter_refs:fetch-pack.c

which shows a list of commits starting with 745f7a8cac (fetch-pack: move
core code to libgit.a, 2012-10-26). So then I did

    git log  -s -L :filter_refs:fetch-pack.c -L :filter_refs:builtin/fetch-pack.c

which fails with

    fatal: -L parameter 'filter_refs' starting at line 1: no match

Philippe Blain (2):
  Documentation/git-log: document accepted line-log diff formats
  Documentation/git-log: mention that line-log regex must match in
    starting revision
