[nosplit eax] has been encoded as [eax*1+0] since 0.98.34.
But this seems like unexpected behavior.
So only when a register is multiplied, that will be treated
as an index. ([nosplit eax*1] -> [eax*1+0])
Document is updated accordingly.

fact, it will also split \c{[eax*2+offset]} into
\c{[eax+eax+offset]}. You can combat this behaviour by the use of
the \c{NOSPLIT} keyword: \c{[nosplit eax*2]} will force
-\c{[eax*2+0]} to be generated literally.
+\c{[eax*2+0]} to be generated literally. \c{[nosplit eax*1]} also has the
+same effect. In another way, a split EA form \c{[0, eax*2]} can be used, too.
However, \c{NOSPLIT} in \c{[nosplit eax+eax]} will be ignored because user's
intention here is considered as \c{[eax+eax]}.
