commit d3605ed7d173aa1c23ad8944cf92e7b810330cb8
Author: Samer Masterson <address@hidden>
Commit: Samer Masterson <address@hidden>
Show files when `initial-buffer-choice' is non-nil
* startup.el (command-line-1): When Emacs is given a file as an
argument and `initial-buffer-choice' is non-nil, display both the file
and `initial-buffer-choice'. For more than one file, show
`initial-buffer-choice' and *Buffer List*. Refactor display-changing
commands out of the command line arg parser.
(initial-buffer-choice): Clarify docstring.
