+Subject: [PATCH] Fix the manual to work with both texinfo-4 and texinfo-5.
+
+Texinfo has been stable for the first 15 years of FFTW's history.
+Then some genius, with too much time in his hands and on a mission to
+deliver the world from the evil of the C language, decided to rewrite
+makeinfo in Perl, the old C version of makeinfo being, as I said,
+evil. The official excuse for the rewrite was that now I can have my
+manual in XML format, as if XML were a feature.
+
+The result of this stroke of genius is that texinfo-5 has different
+rules for macro expansion than texinfo-4 does, specifically regarding
+whether or not spaces after a macro are ignored. Texinfo-4 had weird
+rules, but at least they were constant and internally more or less
+consistent. Texinfo-5 has different rules, and even worse the rules
+in texinfo-5 are inconsistent between the TeX and HTML output
+processors. This situation makes it almost impossible for us to
+produce a manual that works with both texinfo 4 and 5 in all modes
+(TeX, info, and html). The @noindent/@refill hack is my best shot at
+patching this situation.

++ at c rules, but at least they were constant and internally more or less

++ at c produce a manual that works with both texinfo 4 and 5 in all modes
++ at c (TeX, info, and html). The @noindent/@refill hack is my best shot at
++ at c patching this situation.
++
++ at c "@noindent" has two effects: First, it makes texinfo-5 believe that
++ at c the next "@ifinfo" is on a new line, otherwise texinfo-5 complains
++ at c that it is not (even though it obviously is). Second, "@noindent" is
++ at c a macro that eats extra space, and we want this effect because somehow
++ at c macro expansion in texinfo-5 inserts extra spaces that were not there
++ at c in texinfo-4.
++
++ at c "@refill" stops texinfo-5 from interpreting the rest of the line after
++ at c a macro invocation as an argument to "@end tex". For example, in
++ at c "FFTW uses @Onlogn algorithms", somehow texinfo-5 thinks that
++ at c "algorithms" is an argument to "@end tex". "@noindent" would have the
++ at c same effect (as would any other macro invocation, I think), but,
++ at c unlike "@noindent", "@refill" does not eat spaces and does not scan
++ at c the rest of the input file for macro arguments. However, "@refill" is
++ at c deemed "obsolete" in the texinfo-5 source code, so expect this to
++ at c break at some point.
++
++ at c This situation is wholly unsatisfactory, and the GNU project is
++ at c obviously out of control. If this nonsense persists, we will abandon
++ at c texinfo and produce a latex-only version of the manual.
