Remove makeinfo warnings
What
This MR removes a set of warnings produced by makeinfo 7.1.
- warning: @setfilename after the first element (Where texi files contains a setfilename but is not used since file is included from other main texi file. Fixed by removing setfilename.)
- warning: unexpected argument on @ignore line: (Where @ignore line has additional text after command fixed by adding a @c in front of the "comment".)
- warning: unexpected argument on @group line: (Where additional text was on the same line as the group. Fixed by moving the extra text to a separate line assuming that is the intent.)
- warning: @noindent is useless inside of a paragraph (Where a '+' character is the first char on a line. Assuming that is unintentional and the line should just be noindent.)
Why
Gentoo QA is picky and does not like warnings being produced.
Note
This does not attempt to fix the warnings of type:
xemacs-faq.texi:8959: warning: @xref node name should not contain `.'
It seems that is a too big of a chunk for me to attempt to fix at the moment.
