Merge branch 'jc/format-patch' into pu

A new option to send a single patch to the standard output to be
appended at the bottom of a message.  I personally have no need for
this, but it was easy enough to cobble together.  Tests, docs and
stripping out more MIMEy stuff are left as exercises to interested
parties.

* jc/format-patch:
  format-patch: --inline-single
  format-patch: rename "no_inline" field

# Conflicts:
# 	pretty.c

Merge branch 'jn/config-ignore-inaccessible' into pu

When $HOME is misconfigured to point at an unreadable directory, we
used to complain and die. This loosens the check.

I do not think we agreed that this is a good idea, though.

  config: allow inaccessible configuration under $HOME
