Frames created when Emacs is running as a daemon may not have the
"client" frame parameter set, e.g., when:
1. Created from the user's init file.
2. Created via "emacsclient -e" (e.g., "emacsclient -e '(make-frame)'").
The "client" parameter simply indicates that the frame was created by
emacsclient directly (or recursively from another emacsclient frame).
Instead, this commit checks if (a) Emacs is running as a daemon and (b)
the target frame is the "terminal frame". When run as a daemon, Emacs's
terminal frame is always the daemon's initial frame.

Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.

the indicator based in the current faces. Extended condition to set
display-fill-column-indicator-character in graphical displays.
*src/xdisp.c: Fixed some long lines.
